Answer:
x = 2
Step-by-step explanation:
Answer:
x=2
Step-by-step explanation:
3x+5=2x+7 this is the original equation
since we have no clue as to what x could be, we just take a guess.
lets say we used 3.
we would plug in 3 where the x's are and get
3(3)+5=2(3)=7
three times three is 9, 9 plus 5 is 14.
2 times 3 is 6, 6 plus 7 is 13.
since these numbers do not match, 3 cannot be the answer.
if you did these same steps with the number two, you would get 11 as the answer for both, therefore, x=2
3(2)+5 2(2)+7
6 +5=11 4+7=11

Kathy, who plans conferences and parties for a resort, earns $342.22 weekly. Her group medical insurance costs $4,650.00 a year, and the company pays 70% of the costs. How much does she have deducted weekly from her paycheck for medical insurance?
Answer:
Weekly cost= $26.83
Step-by-step explanation:
Giving the following information:
Her group medical insurance costs $4,650.00 a year, and the company pays 70% of the costs.
First, we need to calculate how much she pays a year:
Cost per year= 4,650*0.3
Cost per year= $1,395
Now, the weekly cost:
Weekly cost= 1,395/52
Weekly cost= $26.83

I am thinking of two numbers. Their sum is 1776 and their difference is 1492. What are the numbers?
Answer:
1634 and 142
Step-by-step explanation:
y+x=1776
- (y-x=1492)
equals:
2x=284
÷2 ÷2
x=142
y+142=1776
-142 -142
y=1634
First number and second number are 1,634 and 142.
Given that;
Difference of two number = 1,492
Sum of two number = 1,776
Find:
The numbers
Computation:
Assume numbers are 'a, b'
So,
a + b = 1776 ...... eq1
a - b = 1492 ...... eq2
Eq 1 - Eq2
2b = 284
b = 142
a + b = 1776
a + 142 = 1776
a = 1,634

−3=−1
−3≤−1
−3 −1
−3≥−1
Answer:
The true answer is " -3 < -1.
Step-by-step explanation:
I say this because these numbers are negatives. If you put them on a number line you can see that the bigger numbers are farther from the postitives. Postitive numbers are bigger so whatever is close to them is bigger. So because (-1) is closer to them it would be greater, which is what the symbol "<' states.

WILL GIVE BRAINLIEST PLEASE ANSWER If a circle is dilated by 5/3 and the area of the larger circle is 100pi square cm, then what would be the area of the smaller circle?
Answer:
We have a small circle, that is dilated by a factor of 5/3 creating a larger circle.
If the smaller circle has a diameter D, then after the dilation, the larger circle will have a diameter equal to: (5/3)*D
We know that the area of the larger circle is:
A = 100*pi cm^2.
And the area of a circle of diameter d, is:
a = pi*(d/2)^2
knowing that the diameter of the large circle is (5/3)*D, we can find the value of D.
A = pi*( (5/3)*D/2)^2 = 100*pi cm^2
let's solve this for D:
pi*( (5/3)*D/2)^2 = 100*pi cm^2
( (5/3)*D/2)^2 = 100 cm^2
( (5/3)*D/2) = √(100 cm^2) = 10cm
D/2 = (3/5)*10cm
D = 2*(3/5)*10cm = 12cm.
Then the area of the smaller circle will be:
a = pi*(D/2)^2 = pi*(12cm/2)^2 = pi*(6cm)^2 = pi*36 cm^2
and pi = 3.14
a = pi*36 cm^2 = 3.14*36cm^2 = 113.04 cm^2
find the number of words with or without meaning , which can be made by using all the letters of word ganga
Answer:
There are total 5 letters , of which A occur two times and G occur 2 times
Therefore , The number of permutations starting with A is 4! i.e 24
Thus , 25th word will be start from G i.e GGAAN
By rearranging according to the dictionary , we get
The 26th word will be GGANA
Hence , the 26th word is GGANA
Answer:
30
Step-by-step explanation
total number of letters in the word, n = 5
out of which G and A repeats 2 times each
p1 = p2 = 2
according to the equation of number of permutations,
= [tex]\frac{n!}{p_{1}! p_{2}! }[/tex]
total number of words = 5!/ (2! x 2!)
= 30

-5 + 2(10)
Answer:
The answer is 15
Step-by-step explanation:
-5 + 2(10)
-5+20
=15
Answer:
15
Step-by-step explanation:
PEMDAS:
P - Parenthases
E - Exponents
M - Multiply
D - Divide
A - Add
S - Subtract
When something is in parenthases this means to multiply, like 2(10) means 2 x 10 = 20. Than, - 5 + 20, is the same as 20 - 5.
20 - 5 is 15.
Today only, a table is being sold for $714. This is 85% of its regular price. What was the price Yesterday
Answer:
$840
Step-by-step explanation:
To do this, we can use our formula for solving percents. [tex]\frac{Part}{Whole}[/tex] = [tex]\frac{Percent}{100}[/tex]
The part here is $714 because this is only 85% of the original price which is the whole. Our whole in this problem will be x. As for the percent, we will write 85.
We now have [tex]\frac{714}{x}[/tex] = [tex]\frac{85}{100}[/tex]
To solve this, we use the rules of a proportion. 714 * 100 = 71,400 and then we will divide that by 85 to find x. x = 840
So, the original price was $840.
Answer:
Step-by-step explanation:
714 is 85%
the full price P is 100%
Using the ratio method
714 /85 = P/100
TO find P cross multiply
85P = 714*100
85P = 71400
p = 71400/85 = $840
Ans yesterday's price = $840
or
85% of P = 714
.85*P =714
p = 714/.85
p = $840
