Answer:

x = 5 and y = 1

Step-by-step explanation:

x - 3y = 2 then x = 2 + 3y

Substituting x in: 2x + 5y = 15

2*(2 + 3y) + 5y = 15

4 + 6y + 5y = 15

11y = 15 - 4

11y = 11

y = 11/11

y = 1

Then

x = 2 + 3y

x = 2 + (3*1)

x = 2 + 3

x = 5

I hope it's clear

Is -40 the solution to -12=<img src="https://tex.z-dn.net/?f=%5Cfrac%7Bu%7D%7B8%7D" id="TexFormula1" title="\frac{u}{8}" alt="\f
valentinak56 [21]
Answer: Yes -40 is the answer

Explanation:

-12 = u/8 - 7
8(-12)/8 = u/8 - 8(7)/8
-96/8 = u/8 - 56/8
-96 = u - 56
-u = -56 + 96
-u = 40
u = -40

A circle has a radius of 12 cm. If the radius of the circle is increased by a factor of 7, how many times larger will the circle
-Dominant- [34]

Answer:

The circumference is also 7 times larger

12 cm radius :2*pi*12= 75.43

12*7=84

84cm radius: 2*pi*84= 528

To check if its indeed 7 times larger: 528/75.43 and you'll get 7

If youre looking for the difference between the two: 528-75.43= 452.57
