Answer:
C. 1
Step-by-step explanation:
There is no number before the [tex]x^2[/tex] term and the term is positive, so the coefficient is [tex]1[/tex] (which is the only number we can refrain from writing as a coefficient, hence the reasoning).

Step-by-step explanation:
3/5 + 1/4 = 0.85
0.85 as a fraction is 17/20
So the answer is C
(2t2 - 36t + 162). - (t-9)
Answer:
2t^2 - 37t + 171
Step-by-step explanation:
distrube the - to the (t-9) and then combine like terms
Answer:(2t2 + 27t) - 162 = 0
STEP
2
:
Trying to factor by splitting the middle term
2.1 Factoring 2t2+27t-162
The first term is, 2t2 its coefficient is 2 .
The middle term is, +27t its coefficient is 27 .
The last term, "the constant", is -162
Step-1 : Multiply the coefficient of the first term by the constant 2 • -162 = -324
Step-2 : Find two factors of -324 whose sum equals the coefficient of the middle term, which is 27 .
-324 + 1 = -323
-162 + 2 = -160
-108 + 3 = -105
-81 + 4 = -77
-54 + 6 = -48
-36 + 9 = -27
-27 + 12 = -15
-18 + 18 = 0
-12 + 27 = 15
-9 + 36 = 27 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -9 and 36
2t2 - 9t + 36t - 162
Step-4 : Add up the first 2 terms, pulling out like factors :
t • (2t-9)
Add up the last 2 terms, pulling out common factors :
18 • (2t-9)
Step-5 : Add up the four terms of step 4 :
(t+18) • (2t-9)
Which is the desired factorization
Equation at the end of step
2
:
(2t - 9) • (t + 18) = 0

Theory - Roots of a product
3.1 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.

Find the mean of the data in the dot plot below.
Answer:
2.5
Step-by-step explanation:
Add up all the numbers, then divide by the total amount of the numbers
1+2+3+4=10
10/4=2.5
Answer:
I think 2.5 years
Step-by-step explanation:
Since mean is the same thing as average,
I added them together
1+2+3+4 = 10
then divided by the amount of numbers there are
10÷4=2.5

Answer:
[tex]-\frac{4}{3}[/tex]
Step-by-step explanation:
[tex]-3 \frac{3}{5}[/tex] ÷ [tex]2 \frac{7}{10}[/tex]
Convert both mixed numbers to an improper fraction. This can be done by multiplying the denominator by the "number" part of the mixed number, then adding the result to the numerator.
[tex]- \frac{18}{5}[/tex] ÷ [tex]\frac{27}{10}[/tex]
Now divide the fractions, to divide the fractions, one will find the reciprocal of the recond fractions, and then multiply it by the first fractions. Remember, the reciprocal of a fraction is when one switched the numerator and denominator of a fraction.
[tex]-\frac{18}{5} * \frac{10}{27}[/tex]
[tex]= -\frac{180}{135}[/tex]
Simplify;
= [tex]-\frac{4}{3}[/tex]
At a car dealership, 72 trucks were sold in one month. If 60% of
the total vehicles sold were trucks, how many total vehicles were
sold that month?
A 12
B 132
C 120
D 160
Answer:
The total number of vehicles is: x = 120
Hence, option C is correct.
Step-by-step explanation:
Total trucks that were sold in one month = 72 trucks
Let 'x' be the total number of vehicles.
Given that 60% of the total vehicles sold were trucks.
Thus,
60% of x = 72
60/100 × x = 72
x = [72 × 100] / [60]
x = 120
Therefore, the total number of vehicles is: x = 120
Hence, option C is correct.
Answer:
C 120

Casey wants to buy a gym membership. One gym has a $70 joining fee and cost $35 per month. Another Jim has no joining fee and cost $70 per month. when would Casey pay the same amount to be a member of either gym? How much would he pay?
Answer:
same amount at 2 months. he'd pay 140.
Step-by-step explanation:
35(month) +35(month) =70(joining fee). 70+70=140. that's two months at the first gym.
the second gym is also 140 for the two months because each month is $70. and 70+70=140
