10 = 7 - m
thanksss
Answer:
17
Step-by-step explanation:
10=7-m
m=???
so if you do 10+7 which equal 17 and then do 17-7 you will get ten
m=17
have a good day
Answer:
the answer is -3
Step-by-step explanation:
10 = 7 -m
swap sides so that all the variable terms are on the left hand side
7 - m =10
subtract 7 from both sides
-m + 10 - 7
subtract 7 from 10 to get 3
multiply both sides by -1
m = -3

A game has a spinner with 15 equal sectors labeled 1 through 15. what is p(multiple of 4 or multiple of 7)? 215 15 25 13
The probability that the spinner is multiple of 4 or multiple of 7 is 1/3
What is probability?Probability is the likelihood or chance that an event will occur, Mathematically;
Probability = expected/total
If a game has a spinner with 15 equal sectors labeled 1 through 15, the total outcome is 15
P(multiple of 4) = 3/15 =1/5
Pr(multiple of 7 )= 2/15
p(multiple of 4 or multiple of 7) = 1/5 + 2/15
p(multiple of 4 or multiple of 7) = 5/15 =1 /3
Hence the probability that the spinner is multiple of 4 or multiple of 7 is 1/3

A printing service charges a set-up fee of $11.00 for each order and 15 cents more for each copy. The total cost, c (in dollars), for an order of x copies is given by the following function.
C(x)=11.00+0.15x
What is the total cost for an order of 40 copies?
Answer:
$17 ( 17 USD )
Step-by-step explanation:
C(x)=11.00+0.15x
40 copies:
C(40) = 11+0.15(40)
C(40) = 11+6
C(40) = $17
Therefore, the total cost for an order of 40 copies is $17.

A rectangular patio is 9 ft by 6 ft. when the length and width are increased by the same amount, the area becomes 88 sq ft. ginger is using the zero product property to solve the equation (6 x)(9 x) = 88. what does the value of x in her solutions represent? one possible length and one possible width two possible amounts for the widths two possible amounts for the lengths two possible amounts by which the dimensions were changed
The possible value of x is 2, and the possible dimensions are 8 ft by 11 ft
How to determine the value of x?The equation is given as:
(6 + x) * (9 + x) = 88
Express 88 as a product of two factors
(6 + x) * (9 + x) = 8 * 11
Express 8 and 11 as a sum
(6 + x) * (9 + x) = (6 + 2) * (9 + 2)
By comparison, we have:
6 + x = 6 + 2
9 + x = 9 + 2
This means that
x = 2

a girl saved $13.50 in 6 weeks. at that rate, how long will it take to save $108?
Answer:
48 weeks to save $108
Step-by-step explanation:
$13.50 = 6 weeks so dividing both sides by 6 would find out how much each week
$13.50 / 6 = 6 / 6 weeks
$2.25 = per week
so $2.25 times _____ = $108
2.25x = 108 divided both side by 2.25 to get x alone
x is defined by the number of weeks
2.25x / 2.25 = 108 / 2.25
x = 48 $2.25 times 48 = $108
Solve the system of equations.
5x−4y=−10
−4x+5y=8
Answer:
(- 2, 0 )
Step-by-step explanation:
5x - 4y = - 10 → (1)
- 4x + 5y = 8 → (2)
multiplying (1) by 4 and (2) by 5 and adding result will eliminate x
20x - 16y = - 40 → (3)
- 20x + 25y = 40 → (4)
add (3) and (4) term by term to eliminate x
9y = 0 , thus
y = 0
substitute y = 0 into either of the 2 equations and solve for x
substituting into (1)
5x - 4(0) = - 10
5x - 0 = - 10
5x = - 10 ( divide both sides by 5 )
x = - 2
solution is (- 2, 0 )

Answer:
10∠126.87°
r = 10; θ = 126.87°
Step-by-step explanation:
The coordinate conversion from (x, y) or (x +yi) to (r; θ) can be done using the relations ...
r = √(x² +y²)
θ = arctan(y/x) . . . . paying attention to quadrant

The terminal arm of an angle drawn in standard position rotates in a positive direction through two quadrants of the coordinate plane, and then rotates an additional 25 degrees. What is the measure of the angle?
A. 205°
B. 215°
C. 155°
D. 25°
HELP!!
The measure of the angle is 205°. Then the correct option is A.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
There are 4 quadrants and each quadrant has a measure of 90° angle.
The fact that the orientation is positive indicates that the arm is moving from the first to the second quadrant.
90° + 90° = 180°
The arm has been in the third quadrant due to the additional 25° rotation.
180° + 25° = 205°
The measure of the angle is 205°.

Question 1 True or False: A sector of a circle with a measure of 72 and radius of 12 cm has an arc length of about 15cm. True O False
Step-by-step explanation:
its false
The given statement about the sector of the circle is true.
What is a circle?A circle is a shape or a curve in a plane that has a fixed distance, called the radius, from a given point, called the centre. A circle is also the set of all points that are equidistant from the centre.
Given that we need to check whether a sector of a circle with a measure of 72° and radius of 12 cm has an arc length of about 15cm, or not,
Arc length = central angle / 360° × 2π × radius
= 72/ 360° × 2(3.14) × 12
= 0.2 × 6.28 × 12
= 15.072
≈ 15
Therefore, yes the sector of a circle with a measure of 72° and radius of 12 cm has an arc length of about 15cm.
Hence, the given statement about the sector of the circle is true.

The Normal Distribution
pls help me with my homework!!
thanks,
Using the normal distribution, it is found that the desired measures are given by:
a. Z = -0.67.
b. X = 2.2.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.In item a, we have that [tex]X = 36, \mu = 40, \sigma = 6[/tex], and want to find Z, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{36 - 40}{6}[/tex]
Z = -0.67.
In item b, we have that [tex]\mu = 1.3, \sigma = 0.6, Z = 1.5[/tex], and want to find X, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]1.5 = \frac{X - 1.3}{0.6}[/tex]
X - 1.3 = 0.6 x 1.5

Ailsa is twice as old as Barbara. Ailsa is 5 years younger the candy. the average age of candy ailsa and Barbara is 15. determine candys age
Answer:
Candy is 21 years old
Step-by-step explanation:
If Alisa is 16 years old, that would mean that Barbara would be 8, since she is half of Alisa's age.
If we add 5 to Alisa's age, we get 21. To find the average of their ages, we add them all up, and divide by how many people there are (3).
16+8+21=45
45÷3=15

Ailsa is twice as old as Barbara. Ailsa is 5 years younger than Candy. The average age of Candy, Ailsa, and Barbara is 15.
Let 'x' be the age of Ailsa, 'y' be the age of Barbara, and 'z' be the age of Candy. Then the equations are given as,
x = 2y ...(1)
x - 5 = z ...(2)
(x + y + z) / 3 = 15 ...(3)
From equations (1), (2), and (3), then
x + x / 2 + x - 5 = 45
(5/2) x = 50
x = 20
Then the age Candy is calculated as,
z = 20 - 5
z = 15
Age of Ailsa is 20 years. Then Candy's age will be 15 years.
