ANSWER
10 weeks, $310
EXPLANATION
We have a system of linear equations as both equations need to be satisfied by the same ordered pair (x,y):
y = 25x + 60
y = 30x + 10
We can solve this by substitution. Since y is equal to 25x+60, we can substitute in 25x + 60 for y in the equation y=30x+10
y = 30x + 10
25x + 60 = 30x + 10
Subtract 25x from both sides
60 = 5x + 10
Subtract 10 from both sides and then divide both sides by 5
50 = 5x
x = 10
x represents time in weeks, so 10 weeks.
Find y, the amount of money, by substituting x=10 into either equation.
If we use y = 30x + 10, then
y = 30x + 10
y = 30(10) + 10
y = 300 + 10
y = 310
y = 310 implies $310 so the answer is 10 weeks, $310.
It's just saying that you need to find the volume and surface area and then write them in the designated area, which will be on the side or the bottom.
After doing this for all of them, you have to find two matching numbers and put them together on the same side.
For example:
When you got 722, you can just find another square that might say 722 on square area or volume, then just put the numbers together on the same side.
I don't know if this helped but I hope it did!
Answer:
6.24999999998 or 6.3
Step-by-step explanation:
<span>slope formula, which states that m = (y2 -- y1) / (x2 -- x1).</span>
<span><span>Mary is saving up money to go on a trip. This month, she saved three times as muchmoney as she saved last month. Last month, she saved $24.00. How much money did Mary save this month?</span><span>As much as tells you that you have a comparison.Three times is the multiplier.$24.00 is the amount in the first set.How much money did Mary save this month? is the question you are being asked. To solve, multiply $24.00 x 3.
</span><span>$24.00 x 3 = $72.00.It’s important to clearly show that you understand what your answer means. Instead of just writing $72.00, write:Mary saved $72.00 this month.</span><span>Whenever you finish a math problem of any kind, always go back to the original problem. Think: “What is the question I am being asked?” Make sure that your final answer is a reasonable answer for the question you are being asked.I was asked, “How much money did Mary save this month?” My answer is:<span> Mary saved $72.00 this month.</span>My answer is reasonable because it tells how much money Mary saved this month. I multiplied a whole number by a whole number, so the amount of money Mary saved this month should be more than she saved last month. Seventy-Two is more than 24 . My answer makes sense.</span></span>
