Answer:
Both plans last for 1.25 hours (1 hour 15 minutes)
Step-by-step explanation:
Let x hours be the time needed for plan A and y hours be the time needed for plan B.
On Wednesday there were 5 clients who did Plan A and 3 who did Plan B. Thus, 5x+3y=10.
On Thursday there were 2 clients who did Plan A and 6 who did Plan B. Thus, 2x+6y=10.
Solve the sytem of two equation. Multiply the first equation by 2, the second by 5 and subtract them:
Therefore,
Answer:
144
Step-by-step explanation:
The equation to find c is:
So put -24 into b:
Which simplifies to:
144
So if you want to test this:
x^2 - 24x + 144
is
(x-12)^2
Answer:
I think it’s step 2 where she distributed the exponents incorrectly but she got it right so since no explanation is really needed then I guess it’s step 2.
step 1 where she divided 5 on both sides. Step 3 is also correct since the answer is 0. so step 2 had the mistake.
Answer:
Place value is the value of each digit in a number. For example, the 5 in 350 represents 5 tens,When rounding an integer, all place values to the right of the rounding position are filled with zeros. For example, let's round 8,372 to the hundreds position, which currently contains the number 3. Because the number following the 3 is a 7, we raise the 3 to a 4, and the answer is 8,400.
