Answer:
40.5
Step-by-step explanation:
This answer makes sense because we know that 50% of 90 is 45.
Since 45% of 90 is 40.5, we can self-check our answer.
Hope I helped!

n/8 +12 =64 solve for N.
Answer:
n divided by 8 Plus 12 = 64 n=416
Step-by-step explanation:
Answer:
n = 416
Step-by-step explanation:
n/8 + 12 = 64 (subtract 12 on both sides)
n/8 = 52 (now multiply both sides by 8 so that we can get n by itself)
n = 416
(plug in to check)
416/8 + 12 = 64 (simplify)
52 + 12 = 64 (collect like terms)
64 = 64
Hope this helps!!

Mary had $60 and spent .75 of it for a coat. She then bought a skirt with 50%
of the money that she had left. How much money did she have left after buying
the coat and skirt?
The correct answer is She have left $7.5 after buying the coat and skirt.
Step-by-step explanation
This question is incomplete, the complete question is:
Mary had $60 and spent 0.75 o 3/4 of it on a coat. She then bought a skirt with 50% of the money that she had left. How much money did she have left after buying the coat and skirt?
The answer is $7.50
Explanation:
To know how much money Mary has left after buying the coat we have to multiply $60 by 0.75 as this would help us know the price of the coat.
60 x 0.75 = 45 (price of the coat)
Then we have to subtract 45 from 60 to know how much money she have left after buying the coat.
60 -45 = 15 (Money left)
Then she bought a skirt with 50% of the money that she had left. To know how much money costs the skirt we have to multiply 15 by 0.50. The result of this operation is $7.5, and finally, we have to subtract again $7.5 that she spent on her skirt from $15 and the final result is $7.5

If f(x) = 3x + 2, then find the value of x such that f(x) = -4. A. -14 B. -10 C. -2 D. 14
Answer:
C.
Step-by-step explanation:
f(x) = 3x+2
f(x) = -4
-4 = 3x+2
-4-2 = 3x
-6 = 3x
-6/3 = x
-2 = x
x = -2

Nikki just graduated from high school and would like to buy a car. If she received $3000 in graduation gifts from family friends. She will put this money into a 18 month certificate of deposit until she finds the car of her dreams. The CD earned 10% annually and simple interest. How much will she put towards the down payment and 18 months 1.5 years?
Answer:
$3450
Step-by-step explanation:
Here, P = $3000, N = 1.5 years, R = 10%
[tex]SI = \frac{PNR}{100} \\ \\ SI = \frac{3000 \times 1.5 \times 10}{100} \\ \\ SI = 450 \\ \\ [/tex]
Amount of down payment
= $3000 + $450
= $3450

Solve using fraction strips or common denominators:
1/2 + 3/10=
Answer:
4/5 (or 8/10)
Step-by-step explanation:
the least common denominator of 2 and 10 is 10, so you have to multiply the first fraction (1/2) by 5/5 so that the denominator of that fraction will become 10. Since 3/10 already has 10 as the denominator, you leave it. By adding 5/10 and 3/10 together you'll get 8/10.
If the question asks to simplify your answer, divide the numerator and denominator of 8/10 to get 4/5

In the right ∆ABC, BL is an angle bisector. If LB = 1.2 in and LC = 0.6 in. Find:
- The distance from L to AB.
- m∠ABC
Answer:
Distance of L from AB = 0.6 in.
m∠ABC = 60°
Step-by-step explanation:
Given:
LB = 1.2 in
LC = 0.6 in
We have to find the distance of point L to AB or length of LD.
From right triangle ΔBCL,
Sin(∠LBC) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{LC}{LB}[/tex]
= [tex]\frac{0.6}{1.2}[/tex]
= [tex]\frac{1}{2}[/tex]
m∠LBC = 30° [Since ∠LBC is an acute angle]
Since, ∠LBC ≅ ∠LBA
m∠LBA = 30°
Now from right triangle ΔLDC,
sin(∠LBA) = [tex]\frac{LD}{BL}[/tex]
sin(30)° = [tex]\frac{LD}{1.2}[/tex]
[tex]\frac{1}{2}=\frac{LD}{1.2}[/tex]
LD = 0.6
Therefore, Distance of point L from AB is 0.6 in.
m∠ABC = m∠ABL + m∠LBC
= 30° + 30°
= 60°

[tex]p = 2 \times (( - 3x - 5) + (3 - 4x)) \\ [/tex]

Henry runs up 10.5 flights of stairs. To represent an additive inverse, Henry will have to run down flights of stairs
Answer:
The additive inverse would be -10.5
Henry runs up 10.5 flights of stairs. Then the additive inverse represents running down flights of stairs will be - 10.5.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
The reverse number is a number's complementary inverse. When a number is multiplied by its additive inverse, the result is zero.
