Step-by-step explanation:
6x - 3 + 3x = 60 + 2x
Combine like terms:
6x - 3 + 3x = 60 + 2x
9x - 3 = 60 + 2x
-2x -2x
-----------------------
7x - 3 = 60

x = 9
Hope this helped.
Answer:
9
Step-by-step explanation:
to solve this equation you first have to group the like terms
6x-3+3x=60+2x
6x+3x-2x=60+3
7x=63
then you divide both sides by 7 inorder to remain with the variable x on one side
7x/7=63/7
x=9

Answer:
1_ 129 , 51
2_ b
3_ 40
Step-by-step explanation:
1_ we can represent the bigger angle with x and smaller one with y
and as given, y is smaller than x by 78
so y = x - 78 (1)
as x + y = 180
we put y as we did in (1)
x + x - 78 = 180
so 2x = 258
so x = 129
and y will be 51
2_ from the figure we find the two angles form one angle = 90 degree
3_ from the defenition of complementary angles
m(c) + m(d) = 90
7r + 5 + 8r + 10 = 90
15r + 15 = 90
r = 5
so m(c) will be equal 7*5 + 5 = 40

Answer:
a. 41
b. -31
c. 25/3, no
Step-by-step explanation:
when it says find f(14) the number inside the parenthesis is x, so you just plug that number into the equation which in this case is 3x-1. for c it says find the input if the output is 24. so basically the output is f(x) or y and the input is x. so 3x-1 = 24.

Name the property of real numbers illustrated by the equation.
Answer:
Property
Step-by-step explanation:
Distributive Property(b) Four of the interior angles of a 12 sided polygon are each x °. The other angles are 2xº each. Calculate the value of x.
Answer:
Step-by-step explanation:
Sum of all the angles of 12 sided polygon= (n -2)*180
= (12 - 2 )*180 = 10 * 180 = 1800
Four interior angle each of xº + 8 interior angles each of 2xº = 1800
4*x + 8*2x = 1800
4x + 16x = 1800
20x = 1800
x = 1800/20
x = 90°
Answer:
x = 90
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 12 , then
sum = 180° × 10 = 1800
There are 12 interior angles
Given 4 are x, then 8 are 2x , so
4x + 8(2x) = 1800
4x + 16x = 1800
20x = 1800 ( divide both sides by 20 )
x = 90

Step-by-step explanation:
An irrational number has endless non-repeating digits to the right of the decimal point. They can be written as decimals, but not as fractions.
1632 can be written as 3264/2
0.25 can be written as 1/4
0 could be written as 0/0
but 0.0300300030000 cannot be written as a fraction, and it satisfies the condition of an irrational number having endless non-repeating digits to the right of the decimal point.

Ms. Jacobs is a photographer. For each job she charges $135 for the first hour she works and $100 for each additional hour. Ms. Jacobs charged a total of $535 for a job on Friday. Which equation can be used to determine h, the number of additional hours she worked on this job? MI - A 135h + 100 = 535 B 135 + h + 100 = 535 SI - C 135 + 100h = 535 PSA - D 135h = 535 + 100 is
Answer:
The answer is C, 135 + 100h = 535.
Step-by-step explanation:
H can't be multiplied by 135, since that's only for one hour. That value never changes, so it can't be A. It's not B because that implies that she starts out by charging $235 for the first hour, plus the # of additional hours, which doesn't make sense. And it's not D because the total amount of $ that she receives must EQUAL 535, but there is another number on the same side with 535. Therefore, the only answer that remains is C.
P.S. She worked 4 additional hours.

At the end of a snowstorm, Katherine had 18 inches of snow on her lawn. The temperature then increased and the snow began to melt at a constant rate of 2.5 inches per hour. Assuming no more snow was falling, how much snow would Katherine have on her lawn 4 hours after the snow began to melt? How much snow would Katherine have on her lawn after t hours of snow melting?
After 4 hours of snow melting, there would be 8 inches of snow with the rate of 2.5 inches per hour Katherine would have on her lawn and after t hours the snow would be = 18 - 2.5*t inches.
In this question, the amount of snow melted is required to calculate to know the amount of snow on the lawn, can be calculated by:
the melted amount = rate of melting × timeGiven:
The total amount of snow = 18 inches
Rate of melting = 2.5 inches
Time = 4 hours
Solution:
The amount melted needs to be calculated first in order to find left snow, therefore, putting values in the formula mention above,
the melted amount = rate of melting × time
the melted amount = 2.5 × 4 inches
the melted amount = 10 inches
Then the final amount would have on the lawn = starting amount−melted snow
= 18−10 inches
= 8 inches
Part b) Snow after t hours:
Starting amount= 18 inches
Melted snow= inches per hour×t
= 2.5×t
= 2.5t
Final amount = starting amount−melted snow
= 18 -2.5t
Thus, the correct answer is - 8 inches and 18 -2.5t

fill in the dimensions and angle measures . Are the dashed segments parallel ?
Answer:
To see whether or not two lines are parallel, we must compare their slopes. Two lines are parallel if and only if their slopes are equal. The line 2x – 3y = 4 is in standard form. In general, a line in the form Ax + By = C has a slope of –A/B; therefore, the slope of line q must be –2/–3 = 2/3.
