Step-by-step explanation:
All you're doing is [tex]\frac{5}{8}[/tex] ×[tex]\frac{16}{1}[/tex] or [tex]\frac{5}{8}[/tex] ×[tex]16[/tex]
-
[tex]\frac{5}{8}[/tex] ×[tex]\frac{16}{1}[/tex]
so 5 × 16 = 80
and
8 × 1 = 8
The fraction becomes
[tex]\frac{80}{8}[/tex]
then you simplify ( in this case divide by the botton number/denominator) to get :

12 - 3/4 (d + 16) = negative 5
Answers
Answer: d=20/3
Step By Step:
Step 1, Simplify:
12-3/4(d+16)=-5
(-3/4)d+(12-12)=-5
(-3/4)d=-5
Step 2, Multiply each side by 4/(-3)
(4/-3)*(-3/4)d=(4/-3)*-5
d=20/3
Answer:
[tex]\bold{d=\frac{20}{3} \ or \ 6.66666666667}[/tex]
Explanation:
[tex]\bold{12-\frac{3}{4}\left(d+16\right)=-5}[/tex]
[ Subtract 12 From Both Sides ]
[tex]\bold{12-\frac{3}{4}\left(d+16\right)-12=-5-12}[/tex]
[ Simplify ]
[tex]\bold{-3\left(d+16\right)=-68}[/tex]
[ Divide Both Sides By -3 ]
[tex]\bold{\frac{-3\left(d+16\right)}{-3}=\frac{-68}{-3}}[/tex]
[ Simplify ]
[tex]\bold{d+16=\frac{68}{3}}[/tex]
[ Subtract 16 From Both Sides ]
[tex]\bold{d+16-16=\frac{68}{3}-16}[/tex]
[ Simplify ]

A survey found that 12 out of every 15 people prefer eating out over cooking. If 500 people took the survey, how many people prefer eating out?
Answers
Answer:
400 people
Step-by-step explanation:
15 = 12
500 = x
Cross multiply
15x = 12 × 500
Divide both sides by 15
[tex]\frac{15x}{15}[/tex] = [tex]\frac{12 * 500}{15}[/tex] (* means multiplication if you do not know)
[tex]\frac{12 * 500}{15}[/tex] = 100 × 4= 400 people

The figure below is made of two identical triangular prisms. What is the volume of the figure?
Answers
Answer:
A triangular prism is 1/2 the volume of a rectangular prism with the same dimensions.
V = BH (Base x Width) of a triangular its 1/2BH
The base is 10 x 5, 50 is the base.
The height is 6, and that would be 300 / 2 since it's triangular so its 150 inches squared for one. Since there are 2.
The total volume is 300 inches squared.

Can anyone help me with this answer
Answers
Answer:
18
Step-by-step explanation:
If you take a look at it, its quite similar to the example
Since they are using the same dimensions (1.5) you multiply 1.5 x number x 1.5 again
1/8 as a reciprocal is 8
so you do 1.5 x 8 x 1.5 which gives you 18
Solve the system x+y=0 −2x−y=8 *Answer should be in ( x , y ) form, will give 40 points *
Answers
Answer:
x = -8 and y= 8
(-8,8) is the answer
Answer:
(2,4) (-4,16)
Step-by-step explanation:
Subtract 2 x from both sides of the equation.
y = 8 − 2 x
Substitute 8 − 2 x for y into x ^2 − y = 0 then solve for x .
x = 2 , − 4
Substitute 2 for x into x 2 − y = 0 then solve for y .
y=4
Substitute − 4 for x into x 2 − y = 0 then solve for y .
y=16
Equation form
x = 2 , y = 4
x = − 4 , y = 16
