Answer:
14 children
Step-by-step explanation:
If we know the ration, and we are given the adults, we can set up a proportion in order to solve for the amount of children there are.
5:2=35:x
5x=35*2
5x=70
x=14
There are 14 children
Answer:
(-1, 5)
Step-by-step explanation:
Rearrange the the first equation to have y on one side and all other values on the other side
y = 1 - 4x
since both of the equations are equal to y, set them equal to each other an solve for x.
1 - 4 x = x + 6
-5 = 5 x
x = -1
plug this back into the second equation to get y = 5
Answer:
x = 1,092
Step-by-step explanation:
Duck eggs : chicken heads =
2 : 7
Number of duck eggs = 312
Number of chicken eggs = x
Duck eggs : chicken heads = 312 : x
Equate both ratios
2 : 7 = 312 : x
2/7 = 312/x
Cross product
2 * x = 7 * 312
2x = 2,184
x = 2,184 / 2
= 1,092
x = 1,092
Am I opinion the answers either a or B but I’m pretty sure it’s been
X should be equal to four. You divide 35 by 9 to get the answer (x=4)
