Solve Expression
12(3+5x)+1/4(16x-8)
Answer:
56x + 34
Step-by-step explanation:
12(3 + 5x) + 1/4(16x - 8)
First, use the distributive property. You will get:
(12)(3) + (12)(5x) + (1/4)(16x) - (1/4)(8)
Next, multiply the numbers. You will then have:
36 + 60x + 4x - 2
Now, rearrange the numbers. The variables go in the front. This is what it should look like:
60x + 4x + 36 - 2
Add 60x and 4x, then subtract 36 and 2. This is your answer:
56x + 34

You are creating identical candy bags using 18 chocolate bars, 30 peanut butter cups, and 36 lollipops. What is the greatest number of bags you can fill using all the candy?
You are buying ribbon to make costumes for a school play. Organza ribbon costs $.07 per yard. Satin ribbon costs $.04 per yard. Write an equation to model the possible combinations of yards of organza ribbon and yards of satin ribbon you can buy for $5. List several possible combinations.
Answer:
Let's define the variables:
x = yards of Organza ribbon that you buy.
y = yards of Satin ribbon that you buy.
We know that the price per yard of Organza ribbon is $0.07, this means tat if you buy x yards, the cost will be:
C = x*$0.07
And the cost of the Satin ribbon is $0.04, so if you buy y yards of that ribbon, the cost will be:
C = y*$0.04
Adding that together, the total cost is:
C = x*$0.07 + y*$0.04
Now we know that you pay $5, this means that the total cost is exactly $5, then we have the equation:
$5 = x*$0.07 + y*$0.04
Now we can isolate the variable y to get:
y = ($5/$0.04) - x*($0.07/$0.04)
y = 125 - x*1.75
Now we can just input different values of x to find the correspondent value of y.
This means that:
if x = 0 (0 yards of the Organza ribbon)
then:
y = 125 - 0*1.75 = 0
This combination is:
0 yards of organza, and 125 yards of satin.
Now, if x = 20, then:
y = 125 - 20*1.75 = 90
This combination is:
20 yards of organza, and 90 yards of satin.
if x = 40, then:
y = 125 - 40*1.75 = 55
This combination is:
40 yards of organza, and 55 yards of satin.
The 3 combinations that we found cost exactly $5.

2(n+5)=-2 step by step plz
Answer:
n=-6
Step-by-step explanation:
2(n+5)=-2
distribute
2(n+5)
2xn 2x5
2n+10
2n+10=-2
subtract 10 from both sides
10-10=0
-2-10=-12
2n=-12
divide each side by 2
2n/2=n
-12/2=-6
n=-6
is 7.5 a even or odd number?
Answer:
Only Integers are considered even or odd. So this is not possible to solve. But if you HAD to choose, I believe that it will be even because you round up then its 8 and there you have a even number

Answer:
slope = [tex]\frac{3}{4}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 4, - 2) and (x₂, y₂ ) = (4, 4) ← 2 points on the line
m = [tex]\frac{4-(-2)}{4-(-4)}[/tex] = [tex]\frac{4+2}{4+4}[/tex] = [tex]\frac{6}{8}[/tex] = [tex]\frac{3}{4}[/tex]
What is the solution to this system of linear equations?
x - 3y = -2
x + 3y = 16
O 1.3
O (3.7)
O2-3)
O (-3,-2)
Answer:
(3,7)
Step-by-step explanation:
x-3y=-2 -----equation i
x+3y=16-----equation ii
Subtract the two equations from each other
-6y=-18
-6y/-6=-18/-6
y=3
Substitute for x in equation i
x-3(3)=-2
x-9=-2
x=-2+9
x=7
x=7,y=3
Answer:
X is 7, and Y is 3.
Step-by-step explanation:
Step 1: Add 3y to both sides
x - 3y + 3y = -2 + 3y
x = 3y - 2
Step 2: Substitute 3y - 2 for x in x + 3y = 16
x + 3y = 16
3y - 2 + 3y = 16
Step 3: Simplify both sides of equation
6y - 2 = 16
Step 4: Add 2 to both sides
6y - 2 + 2 = 16 + 2
6y = 18
Step 5: Divide both sides by 6
6y/6 = 18/6
y = 3
Step 6: Substitute 3 for y in x - 3y = -2
x - 3(3) = -2
Step 7: Multiply 3 by 3 for 9
x - 9 = 2
Step 8: Switch sides!
x = 9 - 2
Step 9: Subtract 9 minus 2 to get 7
x = 7
With that we have our final answers: x = 7, and y = 3.
Solve the equation for x. 5(2x − 8) = 90 A) 5 B) 10 C) 13 D) 15
Answer:
c=13
Step-by-step explanation:
Answer:
x=13
Step-by-step explanation:
divide both sides by 5
then move the constant to the right and change signs
2x=18+8
add numbers
divide both sides by 2
Y+2x=7 and x=3+y
Solve each system of equations using substitution
Answer:
y+2x=7 (1)
x=3+y (2)
Replace x = 3+y (2) into (1) => y+2(3+y) = 7
=> y = 1/3 and x = 3+1/3 =10/3

Answer:
slope = [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1,3) and (x₂, y₂ ) = (4, 4) ← 2 points on the line
m = [tex]\frac{4-3}{4-1}[/tex] = [tex]\frac{1}{3}[/tex]

Given:
EFGH is a parallelogram.
Given : EFGH is a parallelogram
Find x and mG.
F
G
(x + 54)
E
(2x - 6)
H
X=?
m
degrees
Answer:
x = 60
m∠G = 114 degrees
Step-by-step explanation:
In any parallelogram, every two opposite angles are equal in measuresIn the given figure
∵ EFGH is a parallelogram
∵ ∠E and ∠G are opposite angles
→ By using the rule above
∴ m∠E = m∠G
∵ m∠E = (2x - 6)°
∵ m∠G = (x + 54)°
→ Equate them
∴ 2x - 6 = x + 54
→ Subtract x from both sides
∵ 2x - x - 6 = x - x + 54
∴ x - 6 = 54
→ Add 6 to both sides
∵ x - 6 + 6 = 54 + 6
∴ x = 60
→ Substitute the value of x in the expression of ∠G to find it
∵ m∠G = 60 + 54
∴ m∠G = 114 degrees
