Solve for x.
8 + x = -4
Answer:
Answer:
x = -12
Step-by-step explanation:
Let's solve your equation step-by-step.
8+x=−4
Step 1: Simplify both sides of the equation.
x+8=−4
Step 2: Subtract 8 from both sides.
x+8−8=−4−8
x=−12
Answer:
[tex]x = 12[/tex]
Step-by-step explanation:
isolate the variable by dividing each side by factors that do not contain the variable
A 24 foot ladder is leaning against the side of a house and is positioned 21 feet
from the house. How far above the ground is the point where the ladder touches
the building?
Answer:
11.7 feet long
Step-by-step explanation:
Formula: a^2+b^2=c^2
a^2+21^2=24^2
a^2+441=576
576-144=135
Square root of 135 is 11.61895004
Round to the nearest tenth is 11.7

Which number can each term of the equation be multiplied by to eliminate the fractions before solving?
2m-3 =2+1m
Answer:
m=5
Step-by-step explanation:
There are no fractions involved to eliminate.
2m-3=2+1m
m=5
Based on the given scenario, the solution to the equation 2m - 3 = 2 + 1m is m = 5.
What is fraction?Fractions are a way of representing parts of a whole. They are written in the form of a numerator and a denominator, separated by a horizontal line.
For example, the fraction 3/4 represents three parts of a whole that is divided into four equal parts.
To eliminate the fractions in the equation 2m - 3 = 2 + 1m, we can multiply both sides of the equation by the least common multiple (LCM) of the denominators of the fractions.
However, in this equation, there are no fractions, so we don't need to multiply by anything to eliminate them. The equation is already in a form that can be solved using basic algebraic techniques.
To solve for m, we can start by moving all the m terms to one side of the equation and all the constant terms to the other side:
2m - 1m = 2 + 3
Simplifying, we get:
m = 5
Therefore, the solution to the equation 2m - 3 = 2 + 1m is m = 5.

Answer:
m∠1 = 30°
Step-by-step explanation:
Properties of a rhombus,
1). Sum of adjacent angles is 180°.
2). Diagonals bisects the angles of a rhombus
By property - (1)
m∠M + m∠N = 180°
120° + m∠N = 180°
m∠N = 180 - 120
= 60°
By property - (2)
Diagonal PM will bisect the angle M.
m∠1 = m∠2
m∠1 = [tex]\frac{1}{2}(\angle N)[/tex]
= [tex]\frac{1}{2}(60)[/tex]
= 30°

Find the number whose 23.2% is 34.8.
Answer:
The required number will be:
x = 150Step-by-step explanation:
Let 'x' be the number
so
23.2% of x = 34.8
23.2% × x = 34.8
23.2/100 × x = 34.8
0.232x = 34.8
divide both sides by 0.232
0.232x/0.232 = 34.8/0.232
x = 150
Therefore, the required number will be:
