Answer:
x = -10
3(x + 4) = -18
3x + 12 = -18
3x + 12 = -18
3x = -18-12
3x = -30
x= -30/3
x = -10
Step-by-step explanation:
[tex]3(x + 4) = - 18 \\ (x + 4) = \frac{ - 18}{3 } \\ (x + 4) = - 6 \\ x = - 6 - 4 \\ x = - 10[/tex]

Select all expressions that are equivalent to 8(5t + 7v).
A. 2(20t + 28V)
B.4(95 + 11v)
C.40t + 7v
D.40t + 56v
The expression 8(5t+7v) is equivalent to the expression 2(20t+28V) and 40t + 56v option (A) and option (D) is correct.
What is distributive property?The distributive property is the property that expresses the distributive law of algebraic multiplication. similarly, in polynomial expression we can use the distributive property for example we can write a(c+b) in the form of (ac+bc).
We have an expression:
= 8(5t+7v)
After using the distributive property, we get:
= 8×5t+8×7v
= 40t + 56v
Applying distributive property in the expression 2(20t+28v), we get:
= 2×20t+2×28v
= 40t+56v
The above expression is equivalent to the given expression.
Again applying distributive property in the expression 4(95+11v), we get:
= 4×95+4×11v
= 380+44v
The above expression is not equivalent to the given expression.
The expression 40t+7v is not equivalent to the given expression.
The expression 40t+56v is equivalent to the given expression.
Thus, the expression 8(5t+7v) is equivalent to the expression 2(20t+28V) and 40t + 56v option (A) and option (D) is correct.

3f = 54
6f = 108
16) k = 69
Step-by-step explanation:
15)
3f + 6f + f = 180
10f= 180
f = 18
16)
42 + k + k = 180
42 + 2k = 180
2k = 138
k = 69

A box contains fiction and nonfiction books. There are 22 fiction books in the box, which is 55% of the total number of books in the box. What is the total number of books in the box?
thank you for helping
Answer:
There are 40 books total
Step-by-step explanation:
you need to set a proportion
The first fraction is 55/100 it's over 100 because it's percent
the other fraction is 22/x the 22 is out of a total number so that's why it's on top and x because you don't know the total number of books
then you multiply diagonally
55×x= 22×100
55x=2,200
Then you solve it like a regular equation by dividing both sides by 55
x=40
Answer:
There are a total of 40 books in the box.
Decrease £740 by 8% .
Answer: 'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
8% = 8/100 = 8 ÷ 100 = 0.08.
100% = 100/100 = 100 ÷ 100 = 1.
Step-by-step explanation:
To calculate percentage decrease:
First: work out the difference (decrease) between the two numbers you are comparing. Then: divide the decrease by the original number and multiply the answer by 100. If your answer is a negative number, then this is a percentage increase.

x = (y/2) - 1
Please help me find the answer.
Answer:
Step-by-step explanation:
Well you didn't give directions on what to solve for,
I'm gonna assume you want to solve for y
x = (y/2) - 1 (add 1 to both sides)
x + 1 = y/2 (multiply both sides by 2)
2(x + 1) = y (distribute the 2)
y = 2x + 2

Answer:
13.3 (rounded in the tenth place)
Step-by-step explanation:
equation: a^2 + b^2 = c^2
What we know :
a = 20^2 = 400
b = what we are looking for
c = 24^2 = 576
Our equation will be looking like :
20^2 + b^2 = 24^2
400 + b^2 = 576
Now we subtract 400 into 576
which equals 176 now we square root it
and get 13.2664 but we gotta square root it and that will lead you to have 13.3 as your answer
Answer:
31.24
Step-by-step explanation:
a^2+b^2=c^2
20^2=400
24^2=576
576+400=976
√976=31.24
