Please help someone!!!
Answer:
[tex]x = 25[/tex]
Step-by-step explanation:
[tex](4x) + (5 + 3x) = 180[/tex]
[tex]4x + 5 + 3x = 180[/tex]
[tex]7x + 5 = 180[/tex]
[tex]7x = 180 - 5[/tex]
[tex]7x = 175[/tex]
[tex] \frac{7x}{7} = \frac{175}{7} [/tex]
[tex]x = \frac{175}{7} [/tex]
[tex]x = 25[/tex]

Answer:
250%
Step-by-step explanation:
Hi there!
In order to solve this problem, we have to divide 200 by 80.
When we do this, we get 2.5. The number in the ones spot, in this case 2, would be worth 200%.
Now we have the 0.5
A half is equivalent to 50%, so we add those two percentages together to get 250%.
I hope this helps!

What is the difference between –11x – 2 and 13x + 5?
24x + 7
-24x + 7
24x + 3
-24x - 7
____________________________
1.) Find the opposite of 13x + 5:To find the opposite of 13x+5, find the opposite of each term.[tex]13x=-13x[/tex][tex]5=-5[/tex]- We do this because when solving this they are in parenthesis, so you must get rid of the parenthesis by turning them negative.
Equation at the end of Step 1:
[tex]-11x-2-13x-5[/tex]2.) Combine −11x and −13x:[tex]-11x+-13x=-24x[/tex]- We do this since we can only have on variable at the end of the problem, so you just combine them if they have the same variable base.
Equation at the end of Step 2:
[tex]-24x-2-5[/tex]3.) Subtract 5 from −2:[tex]-2-5=-7[/tex]- We do this because we need one number left over to get a simplified version of this equation.
Equation at the end of Step 3:
[tex]-24x-7[/tex]____________________________

Answer:
18-Yes 19-No 20-yes 21- yes
Step-by-step explanation:
18
1 to 4, 5 to 20
Yes, this is correct
WE can multiply 1*5 and 4*5 to get 5 to 20
19
Wrong
3 to 11, 1 to 3 isn't correct
For example, if we were to divide 3 by 3 to get one, 11/3 is 2. (6)
So, no
20
2/3 is 2 to 3
14/21 is 14 to 21
If we multiply 2*7 and 3*7, we get 14 to 21
21 25 to 30 is equal to 35 to 42
They just added 7 to both numbers
if we divide ratio 1 by 5, we get 5:6
if we divide ratio 2 by 7 we get 5 to 6

Melanie needs 5,000 chocolates for an event so far she has brought 2 cases of 1,125 chocolates each how many more does she need
Answer:
2750 chocolates
Step-by-step explanation:
Find how much she has bought already:
1,125(2)
= 2,250
Then, subtract this from 5,000
5000 - 2250
= 2750
So, she still needs 2750
Answer:
2,750
Step-by-step explanation:
2 cases of 1,125 chocolates = 2,250 chocolates
5,000 - 2,250 = 2,750 more chocolates needed
(that's also 3 cases of chocolates needed :p)
find x. i need this fast guys
Answer:
5
Step-by-step explanation:
58+78=131
180-131=49
10(5)-1
=5
Answer:
x=5
Step-by-step explanation:
A triangle= 180
53+78+10x-1=180
Combine like terms
130+10x=180
Subtract by 130 on both sides
10x=50
Divide by 10 on both sides
x=5
What is the answer to this problem ?4a4b6(•2a4b5c7)
Answer:
4 * a = 4
a = 1
b * 6
4 * 6
24b
2 a * 4 = 8
b * 5 = c *7
7 * 5 = 35
b = 17.5
C = 17.5
17.5+17.5 = 17.5 * 2 +4a+ b5

The weight of sand and a large bag is 63.4 lb. The sand in the bag is divided equally into 20 small bags what is the weight in pounds of a list of the sand in each small bags
Answer: Weight of sand in each bag = 3.17 lb.
Step-by-step explanation:
Given : Total weight of sand = 63.4 lb
Total small bags = 20
Weight of sand in each small bag = (Total weight of sand ) ÷ (Total bags)
Weight of sand in each small bag = ( 63.4) ÷ (20)
Weight of sand in each small bag = 3.17 lb
Hence, the weight of sand in each small bag = 3.17 lb.
Answer:
3.17lb
Step-by-step explanation:
Given that f(x) = 4x - 7 and g(x) = 4x, find a simplified expression for
f(f(x)).
Given:
[tex]f(x)=4x-7[/tex]
[tex]g(x)=4x[/tex]
To find:
The expression for f(f(x)).
Solution:
We need to find f(f(x)).
[tex]f(f(x))=f(4x-7)[/tex] [tex][\because f(x)=4x-7][/tex]
[tex]f(f(x))=4(4x-7)-7[/tex] [tex][\because f(x)=4x-7][/tex]
Using distributive property, we get
[tex]f(f(x))=4(4x)+4(-7)-7[/tex]
[tex]f(f(x))=16x-28-7[/tex]
[tex]f(f(x))=16x-35[/tex]
Therefore, the expression for f(f(x)) is [tex]f(f(x))=16x-35[/tex].

Answer:
-10 1/2, -8 1/2, -4 1/2, 4 1/2
Step-by-step explanation:
Basically to get the answer, its easiest to convert the fraction to a decimal then put it on a number line. 1/2=0.5.
Answer:
-10 1/2, -8 1/2, -4 1/2, 4 1/2
Step-by-step explanation:
Something that helps is a number line, put 0 in the middle and put positive numbers on and negitive numbers so you can see what is smaller. For example:
least to greatest
