Question 3 is- B. 8 ounces
Step-by-step explanation:
If I can eat 2/5 of a pizza in 1/7 hour how many can I eat in one hour
Answer:
2 and 4/5
Step-by-step explanation:
If you ate 2/5 of a pizza in 1/7 of an hour then you need to multiply 2/5 by 7
Start by converting 7 into a fraction
7 = 7/1
then multiply the top and bottom of the fractions
2 * 7 = 14
5 * 1 = 5
2/5 * 7/1 = 14/5
Convert 14/5 into a mixed number
14/5 = 2 and 4/5
5z-8=-28 solve for x
Answer:
z = -4
Step-by-step explanation:
I'm going to assume you mean solve for z.
5z - 8 = -28
add 8 to both sides.
5z = -28 + 8
5z = -20
divide both sides by 5
z = -4
Answer: The answer would be −4.
First add eight to both sides.
5z−8+8=−28+8
5z=−20
Now divide both sides by five.
5z divided by five = -20 divided by 5.
z=−4

18x + 3 squared is 81 what is x?
Answer:
x=1/3
Step-by-step explanation:
(18x+3)^2=81
square root both sides
18x+3=9
subtract 3 from both sides
18x=6
divide 18 on both sides
x=1/3
Find the extraneous solution of the equation |9 – 4x|= -5x .

Write the equation of the line below, in slope-intercept form.
Answer: y=3x-3
Step-by-step explanation: Formula: y=mx+b The slope is m which is 3, rise over run, and b is the y-intercept which is -3.
Answer:
y=3x+-3
Step-by-step explanation:
the slope is 3/1 which is 3.
the y intercept is the point at which theine crosses te y axis so it's-3
y=mx+b
y=3x+-3

(-2,-9) and (7,3)
Help?!
Answer:
The answer is 15.
Step-by-step explanation:
d = sqr. root of (x_2 - x_1)^2 + (y_2-y_1)^2}
= sqr. root of 7- - 2 ^ 2 + 3 - - 9 ^ 2
= sqr. root of 9 ^ 2 + 12 ^ 2
= sqr. root of 81 + 144
= sqr. root of 225
= 15

Find the Perimeter of the figure below, composed of an isosceles trapezoid and one semicircle. Rounded to the nearest tenths place
Answer:
4π + 33 or 45.6
Step-by-step explanation:
For this question, you need to identify the perimeter of the semicircle and the 3 sides of the trapezoid.
The perimeter of the semicircle would be (this is the equation for a circle divided by two):
(2πr)/2 or (πd)/2
To figure this out, you don't need to know the radius, because you can just use the diameter, in which case if you plug it in you would get:
(8π)/2
→ 4π
Now you would just add the perimeter of the semicircle to the perimeter of the 3 sides of the trapezoid to get:
4π + (10+13+10)
→ 4π + 33
Now all you'd need to do is round 4π to the tenths place to get:
12.6 + 33
→ 45.6

Answer:
A. x=35
B. C= 59 degrees
Step-by-step explanation:
Since both angles have the same measurement you set them equal to each other as so & solve for x
3x+16=5x-54
16=2x-54
70=2x
x=35
Now we plug 35 into one of the equations
3(35) + 16
105+ 16 = 121 degrees
Since angle C is a supplementary angles you do 180-121= 59 degrees
