4 + 5 x 6
Multiplication is before Addition so you would multiply 5 times 6 first.
Then there would be just 4 + 30, and when you add 4 + 30, you would get 34

Chuck has $2,345 he is buying gift cards for some of his friends and each gift card costs $85 whats the greatesy amount of gift cards can he buy and how much money will he have left?
Answer:
$50Step-by-step explanation:
Chuck has $2,345 in total
if one gift card cost $85
we want to find the total number of cards that $2,345 can buy.
so we have to divide $2,345 by $85
= $2,345/85
=27card in total
27*85=$2295
the amount left is
= $2,345 -$2295
=$50
therefore the amount left is $50

ANSWER QUESTION 1 THROUGH 2 AND SHOW HOW YOU GOT YOUR ANSWER.
(1) A farm has 15 rows of fruit trees with 7 trees in each row. The last 4 rows of trees are cherry trees. The remaining trees are orange trees. How many orange trees are on the farm?
(2) At the bakery, there are 5 rows with 12 chocolate chip cookies on each tray. There are 2 trays with 14 cookies on each tray. If 7 cookies are sold. How many cookies are left?
Answer:
Step-by-step explanation:
1) If a farm has 15 rows of fruit trees with 7 trees in each row, the total number of trees in the farm will be 15*7 = 105 trees
If the last four rows of trees are cherry trees, the total numner of cherry trees will be 4 * 7 = 28 trees
Let the total trees in the farm = number of cherry trees + orange trees
orange trees = total trees - cherry trees
orange trees = 105 - 28
orange trees = 77 tress
Hence there are 77 orange trees in the farm
2) If at the bakery, there are 5 rows with 12 chocolate chip cookies on each tray, the total number of cookies on the tray will be 5 * 12 = 60 chocolate cookies
Also if there are 2 trays with 14 cookies on each tray, the total cookies on both tray s will be 2 * 14 = 28 cookies
If 7 cookies are sold, the number of cookies left will be 28 - 7 = 14 cookies
Hence 14cookies will be left over
In which number does the digit 8 have a value that is ten times as great as the value of the digit 8 in the number 178,643? 84,093 158,936 314,892 810,725
Answer: 84,093
Step-by-step explanation:
To find : The number that have a value that is ten times as great as the value of the digit 8 in the number 178,643
The place value of 8 in 178,643 = 8,000 or eight thousand
Ten times eight thousand = 10 x 8000=80,000
From the given numbers, only 84,093 has that place value .
Hence, the correct number is 84,093

Company A rents copy machines for $300 a month plus $0.05 per copy. Company B charges $600 a month plus $0.01 per copy. For which number of copies do the two companies charge the same amount?
Answer:
7,500 copies
Step-by-step explanation:
First, write the problems as equations. There will be one variable: copies (c):
Company A: .05c + 300
Company B: .01c + 600
In order to find when the companies charge the same amount, Company A = Company B. Using the transitive property you get:
Company A = Company B
.05c + 300 = .01c + 600
Now, you just need to solve for c:
.05c + 300 = .01c + 600
.05c = .01c + 300
.04c = 300
c = 7,500
In conclusion, the companies will charge the same amount of money when 7,500 copies are made in a month.
Find the zeroes of the polynomial f(x)= 2x² - 5x + 3 and verify the relationship between the zeroes and the coefficients.
The polynomial
f(x) =2ˣ² - 5x + 3
Find :zeroes of the polynomial f(x)= 2x² - 5x + 3
Solution :By factorizing we have ,
→ 2x² - 5x + 3
→2x² -2x - 3x + 3
→2x(x-1)-3(x-1)
→(2x-3)(x-1)
Now the zeroes are
→ 2x - 3 = 0 and → x - 1 = 0
→ x = 3/2 and → x = 1
Verification of relation
Sum of the zeroes = -b/a
⇒ 3/2 + 1 = -(-5/2)
⇒ (3+2)/2 = 5/2
⇒ 5/2 = 5/2
Product of the zeroes = c/a
⇒ 3/2×1 = 3/2
⇒ 3/2 = 3/2
Verified
I hope it will help you.

Determine if the function is linear.
Show your work.
Answer:
Yes it is
Step-by-step explanation:
In order to find it, you just need to find the slope which the equation is y2-y1/x2-x1
Giving you the slope to be -5/3
and the b value is 16 bc it is 16 at 0
slope equation is y= mx + b
plug -5/3X+16 into your graphing calculator and see that it is a straight line and boom.

What are measures of 21 and 22?
Answer:
B. m<1=52, m<2=60
Step-by-step explanation:
to find angle 1 you need to subtract 128 from 180 which gives you 52. Then you add 68 and m <1 which gives you 120 and subtract that from 180 giving you 60 for m<2

Find the Unit Rate: 300 miles in 5 hours
Answer:
60 miles per hour
Step-by-step explanation:
This is a fraction equal to
300 miles ÷ 5 hours
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 5
300 miles ÷ 5
5 hours ÷ 5
=
60 miles
1 hour
=
60 miles

Answer:
the independent variable is time and the distance dependent variable is distance.
Step-by-step explanation:The question is asking for the definition of independent and dependent variable. An independent variable is a variable that is manipulated to determine the value of a dependent variable while a dependent variable is the variable that is been measured in an equation. From the given question, the independent variable is time while the distance covered is the dependent variable.
BUILDING CODE A city has a building code that limits the height of buildings around the central park . The code says that all buildings must be less than 0.1x in height where x is the distance of the building from the center of the park and y is height in feet. Assume that the par center is located at 0. Write an inequality that represents the building code (1 pt)
Answer: 0= y x (x)
Step-by-step explanation: y x x ≠ 0.1x
The required inequality for the height of the building around the park should be y < 0.9x.
Given that,
A city has a building code that limits the height of buildings around the central park. The code says that all buildings must be less than 0.1x in height where x is the distance of the building from the center of the park and y is height in feet. Assume that the par center is located at 0.
Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Here,
The height of all the buildings must be,
y < x - 0.1x
y < x(0.9)
y < 0.9x
Thus, the required inequality for the height of the building around the park should be y < 0.9x.

Answer:
3/5, -12 12/15, 51/125
Step-by-step explanation:
just did it
Answer:
3/5; -12 12/25; 51/125
Step-by-step explanation:
Write the first one just like you would say it. You would read 0.6 as six tenths, therefore your answer is 6/10, but don't forget to simplify to 3/5.
Next, you have -12.48. -12 is going to be your whole number. However, you still have 0.48 left so you would write it just how you would say it. You would say it as forty-eight hundredths which is why you would write it as 48/100. Now you just have to simplify it into 12/25. Thus, your final answer would be -12 12/25.
Finally, you have 0.408 which is read as four hundred eight thousandths. Your fraction would then be 408/1000. Now simplify to 51/125.
A quadratic equation has an axis of symmetry at x = 7 and has a
maximum value at -3. Write the equation.
g(x) = -3(x – 7)?
O g(x) = -(x + 7)2 – 3
O g(x) = -(x – 7)2 – 3
og(x) = (x – 7)2 – 3
Answer:
g(x) = (x - 7)² - 3
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k) = (7, - 3) and a = 1, thus
g(x) = (x - 7)² - 3
-3x + 6 = 21 solve for x and show work.
