Add 6 left and right and get: g-6+6 > -1+6 =>
g>5
Answer:
15$
Step-by-step explanation:
15$
so.. .whatever those amounts are, of "x" and "y", for the mixture,
they must add up to 100 grams, or x + y = 100
and the titanium percentage of that sum, must yield a 13 grams of titanium on those 100 grams
thus
do the substitution, and solve for "x",
what's "y" amount? well, y = 100 - x
If I'm understanding this correctly, you want us to make it into a fraction?
70% = 70 per hundred.
Which means it's 70/100
70/100 or 7/10
Answer:
12,000psi
Step-by-step explanation:
Given the 7 days strength of a concrete to be 3000psi, to calculate the estimated mean28-day strength of this concrete the following equality equation is applied
7 days strength = 3000psi
28days strength = y
To get y, we will Cross multiply
7 × y = 28×3000
7y = 28×3000
7y = 84000
Divide both sides by 7
7y/7 = 84000/7
y = 12000
hence the estimated mean 28-day strength of this concrete is 12,000psi
