Answer:
4 1/4 + 3 1/4 = 7 1/2
Step-by-step explanation:
To make 1/4 to 1/2 You would need 1/4, because 2/4 make 1/2
7-4= 3 so therefore you would have 3 1/4
Answer:
$50,000
Step-by-step explanation:
Let x = car sales
We multiply x by 0.02 since she earns 2% along with the added $2500 so that she can end up with $3500
3500 = 0.02x + 2500
Subtract 2500 from both sides
3500 - 2500 = 0.02x + 2500 - 2500
1000 = 0.02x
Divide both sides by 0.02
1000/0.02 = 0.02x/0.02
x = 50000

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²
- a is a leg
- b is another leg
- c is the hypotenuse<u>
</u>
Step-by-step explanation:
<u>Step 1: Identify</u>
Leg <em>a</em> = 7.5
Leg <em>b</em> = 10
Hypotenuse <em>c</em> = <em>c</em>
<em />
<u>Step 2: Solve for </u><em><u>c</u></em>
- Substitute in variables [Pythagorean Theorem]: 7.5² + 10² = c²
- Rewrite: c² = 7.5² + 10²
- Evaluate exponents: c² = 56.25 + 100
- Add: c² = 156.25
- [Equality Property] Square root both sides: c = 12.5
Answer:
10: m=2/3ns
12: g=h-f/5
Step-by-step explanation:
Find the answer for 15:
462,371 * 10 = 4,623,710
(millions place)
Find the answer for 16:
How many hundreds to make a thousand?
10! because 371 * 10 = 3,710
(10 times)
