One number is 14 more than another number. Their sum is 58. Find the numbers.
Numbers are 36, 22
What is an equation?An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra. Algebra is used in mathematics when you do not know the exact number in a calculation.
Given
One number is 14 more than another and their sum is 58.
Let one number be x
Another number will be x + 14
Rewriting the equation in mathematical form
⇒ [tex]n+ (n+4) =58[/tex]
⇒ [tex]2n +14 =58[/tex]
⇒ [tex]2n = 58-14[/tex]
⇒ [tex]2n=44[/tex]
⇒ [tex]n= \frac{44}{2}[/tex]
⇒ [tex]n=22[/tex]
⇒ [tex]n+14=22+14=36[/tex]
Hence, numbers are 36, 22

120 ≤ 12 k + 29 need help
The answer is [tex]k[/tex] ≥ [tex]\frac{91}{12}[/tex]
First, you must flip the equation
[tex]12k+29[/tex] ≥ [tex]120[/tex]
Then, you must subtract 29 on both sides
[tex]12k[/tex] ≥ [tex]91[/tex]

Answer
18
Step-by-step explanation:
m+7−5=20
Step 1: Simplify both sides of the equation.
m+7−5=20
m+7+−5=20
(m)+(7+−5)=20(Combine Like Terms)
m+2=20
m+2=20
Step 2: Subtract 2 from both sides.
m+2−2=20−2
m=18

Please classify the following equations as parallel, perpendicular, intersecting, or coinciding (same line):
y = 3x + 2
9x - 3y = -6
Answer:
Intersecting
Step-by-step explanation:
Parallel lines means it will have the same slope, and perpendicular means the slope will be it's reciprocal, so the slope would be 1/3 x instead of 9x. Conciding means it's the exact same equation, so the answer has to be intersecting.

What do degrees measure?
A. The type of angle
B. The length
C. The orientation
D. The incline
The degrees measure the incline because the degree measures an angle which is the measure of incline option (D) is correct.
What is an angle?When two lines or rays converge at the same point, the measurement between them is called an "Angle."
It is given that:
The measuring unit is the degree
The measurement can be defined as the numerical quantity that gives an idea about object length, width, and many more. It can be used to compare two objects.
As we know from the definition of the angle; two lines or rays converge at the same point, and the measurement between them is called an "Angle."
The degree measures an angle which is the measure of incline.
Thus, the degrees measure the incline because the degree measures an angle which is the measure of incline option (D) is correct.

For the first equation 6v+38≤ -4
The answer would be v≤-7
and for the second equation 2(v+3)≥-2
the answer would be v≥-4
Step-by-step explanation:
6v+38≤ -4
Subtract 38 from both sides
6v+38-38≤-4-38
Simplify
6v≤-42
Divide both sides by 6
6v/6≤-42/6
Simplify
v≤-7
SAME THING FOR THE OTHER
2(v+3)≥-2
Divide both sides by 2
2(v+3)/2≥-2/2
Simplify
v+3≥-1
Subtract 3 from both sides
v+3-3≥-1-3
And finally, simplify
v≥-4
