Answer:
Jerry collected 126 stamps.
Renee collected 487 stamps.
Step-by-step explanation:
Let Jerry be J and Renee be R
Eq1: R=4J-17
Eq2: 613=R+J
Rearrange the second equation to isolate J:
J=613-R
Sub this new equation into Eq1 and solve for R:
R=4(613-R)-17
R=2452-4R-17
5R=2435
R=487
Sub R=487 into Eq2 to solve for J
613=487+J
J=126
Factor 10 out of 10x+40. So, the correct answer is 10(x+4).
Hope this helps!:)

51. 2
Step-by-step explanation:
According to the Order of Operations [GEMS\BOMDAS\PEMDAS etc.], in this case, evaluate everything in grouping symbols first, then evaluate the exponents to avoid confusion:
I am joyous to assist you anytime.
1.) There are 6 numbers you can roll on a standard dice: 1, 2, 3, 4, 5, 6
There are 3 odd and 3 even. Keep in mind that an odd plus an odd will always be even and an even plus an even will always equal an even. Only if you add an odd and an even will you get an odd.
The chances of getting an even sum are much higher which is why you should choose even.
3.) The formula for finding the area of an equilateral triangle is (<span>√3)/4(a^2) where a is just a side length.
Because the perimeter is 12 and each side of an equilateral triangle is equal, we can divide 12 by 3 sides and get each side is 4. Plug in 4 for a.
</span>(√3)/4(4^2) = (√3)/4(16)
Because (√3)/4 = (1 x √3)/4,
(√3)/4(16) is equal to (16 x √3)/4
You have to divide (16 x √3) by 4. 16/4 = 4, and you only need to divide once to. We get 4√3 as the final answer.
