Number 7 is not a factor of the number 49t + 30.
<h3>What is defined as the factor?</h3>
A factor is a number which divides another number by itself and leaves no remainder.
In other sayings, if multiplying 2 whole numbers yields a product, the numbers being multiplied are factors of a product because of product is divisible by them.
- Every integer has a limited number of factors.
- The factor of a number is often less than or equal to that number; it can never be greater than the number.
- With the exception of 0 and 1, each integer has at least two factors: 1 as well as the number itself.
- Division and multiplication are used to find factors.
For the given problem,
The equation is given as 49t + 30
For any value of t the number (49t will get completely divide by 7 leaving no remainder behind).
But 30 is not the factor of 7 as it will leave the remainder 2.
Thus, adding number 30 with 49t will result in a number which is not completely divisible by 7.
Thus, 7 is not a factor of number 49t + 30.

Answer:
Step-by-step explanation:
a) increase
Increase = 200 -130 = 70
Percent increase = (70/130)*100 = 70*100/130 = 7*100/13
= 700/13
= 53.85%
The number 1.52 can be expressed using this fraction 152/100. This fraction is equal to 38/25 when reduced to lowest terms. This fraction is also equal to 1 13/25 when expressed as a mixed number.
Answer:
x=26
Step-by-step explanation:
You have already set up an equation for us.
75+105=180
This is because a line is 180 degrees.
This said, we can set up an equation to find x.
4x+1=105
Isolate x by first subtracting 1 from both sides.
4x=104
Divide both sides by 4.
x=26
Answer:
(x-3) is the correct expression
Step-by-step explanation:
To factor you split the expression apart -
x² + 2x – 15
This breaks up to (x+5)(x-3)
If you multiply (FOIL) these you get your expression x² + 2x – 15
Your answer choices do not include (x+5) so it must be (x-3)
