Answer:
h= 14
Step-by-step explanation:
7h-5(3h-8)= -72 PEDMAS Parenthesis first
7h-15h+40= -72 combine like terms
-8h+40= -72 subtract 40 from both sides
-8h=-112 divide by -8
h=14
The required simplified solution of the given expression is h = 4.
Given that,
A number of instruction has been added in the question, guiding the solution of the given expression.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Given expression,
7h-5(3h-8) = -72
Simplify,
7h -5×3h - 5× -8 = -72
7h -15h + 40 = -72
8h = -72 + 40
-8h = -32
h = 4
Thus, the required simplified solution of the given expression is h = 4.

Write the solution to the inequality
Answer:
No answer.
Step-by-step explanation:
- 8m - 12 > -5m + 40 - 3m + 21
combine terms
-8m - 12 > -8m +61
add 8m to both sides
-12 > 61
negative 12 is not greater than 61

(0, 2) is the y intercept of the given graph, option B is correct.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The line is passing through the points (3, 0) and (0,2)
We have to find the slope
m=2/-3
=-2/3
Now let us find y intercept
0= -2/3(3) +b
b=2
Hence, (0, 2) is the y intercept of the given graph, option B is correct.

Car Survey in a survey of 1,800 people who owned a certain type of car, 1,080 said they would buy
that type of car again. What percent of the people surveyed were satisfied with the car?
Answer: 60%
Step-by-step explanation:
First you have 1,080 satisfied out of 1,800.
Then you divide 1,080/ 1,800.
When you divide you get .6
Finally move the decimal 2 places to the right and you get 60 which is 60%.
how much is the arc of a circle if the angle is 70°
Answer:
siriously i dont know cuz im learning this in maths
area
perimeter
arc
Answer:
We also know that the sum of the measures of arcs AD, AB, CD, and BC must be 360 degrees, because there are 360 degrees in a full circle. Because AD = 2AB, we can substitute 2AB for AD. This means the measure of arc AB is 70 degrees, and the measure of arc AD is 2(70) = 140 degrees.

If the weight of a package is multiplied by 3/4 the result is 54 pounds find the weight of the package?
Answer:
72
Step-by-step explanation:
In order to find the solution to this problem, you would first need to divide 54 by 3, than multiply by 4. You could also multiply 54 by the reciprocal of 3/4, which is 4/3.
1 half + 10 = 1 fourth + 54.

(18z + 3+5z - 3)\degree = 161\degree \\\\
(23z)\degree = 161\degree \\\\
23z = 161\\\\
z = \frac{161}{23} \\\\
\huge \red {\boxed {z = 7}} \\\\

Mabel scored 19 points more on her math test than Nancy. Phoebe scored 10 points less on her math test than Nancy. If Phoebe scored 23 points, how many points did mabel score.
The point that is scored by Mabel will be 52 points.
Based on the information given, since Phoebe scored 10 points less on her math test than Nancy and scored 23 points, then Nancy will have:
= 10 + 23 = 33 points
Since Mabel scored 19 points more on her math test than Nancy, then, the point that is scored by Mabel will be:
= 33 + 19
= 52 points

A scale on a map shows that 2.5 centimetres represents 15 kilometres what number of actual kilometres are represented by 17.5 centimetres on the map
Answer:
105km
Step-by-step explanation:
From the above question, the scale is
2.5 cm = 15km
Therefore,
17.5 cm = x
We Cross Multiply
2.5cm × x = 15km × 17.5 cm
x = 15km × 17.5cm/2.5
x = 262.5/2.5
x = 105 km
Therefore, the number of actual kilometres that are represented by 17.5 centimetres on the map is 105 kilometres.
Marie can find the volume of a cube by using the formula V=s exponent 3 where s repersents the side length of the cube if marie's cube has a side length of 2-1/2 centimerters what is the volume of her cube? WRITE AS A FRACTION
Answer:
125 / 8 centimeters
Step-by-step explanation:
Given:
V = s³
Where,
V = volume of the cube
s = side length of the cube
if marie's cube has a side length of 2 1/2 centimerters
That is,
s = 2 1/2 cm
V = s³
= (2 1/2)³
= (5/2)³
= 125 / 8 centimeters
NOTE:
(5/2)³ = 5³ / 2³
= 5*5*5 / 2*2*2
= 125 / 8
