14-2 is 12÷1.5 is 8. It will take 8 years for the tree to be 14 foot tall
Answer:
No.
Step-by-step explanation:
For there to be a equal sign, it will mean that both sides will have to have the same exact amount. If it is expressions on both sides, then the expressions must, when combined, equal to each other.
In this case, there is not given operation that will allow for both numbers to equal each other, and 17.8 is 10 less than 18.8, therefore it is not reasonable.
17.8 ≠ 18.8
Answer:
67667.7
Step-by-step explanation:
let the number= Y
the question simply means that 0.15 percent of Y which give 10.5
so, let find Y:
0.15% of Y 10.15
<h3>Stating the mathematical equation</h3>
0.15/100×y = 10.15
0.0015y= 10.15
divide bothsides by 0.0015
0.0015y/0.0015= 10.15/0.0015
y=6766.66
y= 6766.7 approximately
<h3>therefore, 0.15% of 6766.7 is 10.5</h3>
Answer:
(3, 5)
Step-by-step explanation:
y = 2x - 1
3x + 2y = 19
In the second equation, substitute 2x - 1 in for y, since y equals 2x - 1 in the first equation. Solve for x.
3x + 2(2x - 1) = 19
3x + 4x - 2 = 19
7x - 2 = 19
7x - 2 + 2 = 19 + 2
7x = 21
7x/7 = 21/7
x = 3
Pick the first equation to solve for y since it says y =. Substitute 3 in for x.
y = 2x - 1
y = 2(3) - 1
y = 6 - 1
y = 5
