Answer:
the number of grams of zinc contain is 78
Step-by-step explanation:
The computation of the number of grams of zinc contain is shown below:
Given that the ratio of zinc to copper is 3:16
And, the jar of the chemical has 416 grams copper
So, the number of zinc grams would be
here we assume the zinc grams be x
Now the equation would be
3 ÷ 16 = x ÷ 416
Now applied the cross multiplication
16x = 416 × 3
x = (416 × 3) ÷ 16
= 78
Therefore the number of grams of zinc contain is 78
I've been answering lots of questions and this one's hard
x+(x-2)=7 cab be used to determine the value of x.
Step-by-step explanation:
Given,
Heidi has x donations.
Grandpa Case has 2 fewer donations than Heidi.
Fewer means subtraction.
Grandpa has = x - 2
They have 7 donations in all.
Heidi's donations + Grandpa's donations = Total donations
x+(x-2)=7
x+(x-2)=7 cab be used to determine the value of x.
