What number would you multiply the second equation by in order to eliminate the x-terms when adding to the first equation? What number would you multiply the first equation by in order to eliminate the y-terms when adding to the second equation?
Answer:
1. Multiply (2) by 2 to eliminate the x-terms when adding
2. Multiply (2) by 3 to eliminate the y- term
Step-by-step explanation:
Use this system of equations to answer the questions that follow.
4x-9y = 7
-2x+ 3y= 4
what number would you multiply the second equation by in order to eliminate the x-terms when adding the first equation?
4x-9y = 7 (1)
-2x+ 3y= 4 (2)
Multiply (2) by 2 to eliminate the x-terms when adding the first equation
4x-9y = 7
-4x +6y = 8
Adding the equations
4x + (-4x) -9y + 6y = 7 + 8
4x - 4x - 3y = 15
-3y = 15
y = 15/-3
= -5
what number would you multiply the second equation by in order to eliminate the y- term when adding the second equation?
4x-9y = 7 (1)
-2x+ 3y= 4 (2)
Multiply (2) by 3 to eliminate the y- term
4x - 9y = 7
-6x + 9y = 12
Adding the equations
4x + (-6x) -9y + 9y = 7 + 12
4x - 6x = 19
-2x = 19
x = 19/-2
= -9.5
x = -9.5

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

Four friends purchase a pineapple for $2.89 and 18.4 pounds of peaches. The peaches cost $1.75 per pound. The friends share the total cost equally.
What amount does each person pay?
$8.77
$9.31
$21.34
$35.09
Answer:
$8.77
Step-by-step explanation:
Total cost = 2.89 + 18.4*1.75
= 2.89 + 32.2
= $35.09
Amount paid by each person = $35.09/4
= $8.77

parallel means same x value when talking about graphs
Answer:
y=3x

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
Which inequality is a true statement?

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.
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
