Answer:

300+90+9

-45=0+40+5

Step-by-step explanation:

399-45=354

Answer:

131

Step-by-step explanation:

1. Do the brackets first because BEDMAS -> 5^2+2 x 53

2. Do the exponents -> 25 + 2 x 53

3. Multiply and divide (left to right) -> 25 + 2 x 53 -> 25 + 106

4. Add and subtract that -> 131

Hope this helps! :)

Answer:

t = 7/2

Step-by-step explanation:

t:7 = 1:2

t/7 = 1/2

Cross Multiply both sides

2t = 7*1

 t = 7/2

Answer:

y-intercept: -3.

Slope:7/5

Step-by-step explanation: Y-intercept: The line crosses the y-axis at y=-3.

Slope: If you start from the point on the y-axis, -3, and count up 7 units, you reach 4 and then count right 5 units to reach a part of the line which touches a point. You go up 7 and go right 5 units. Therefore, the slope is 7/5. You go up, or rise, 7 units, and go right, or run, 5 units.

hi there user! Looks like your looking for help, so Mizuki came here to help you!

the answer is:

m is 2/3

The whole work I did:

m + 4 ÷ 3 = 2

m + 4/3 = 2

m + 4/3 - 4/3 = 2 - 4/3

m = 6/3 - 4/3

m = 2/3

Anyways hope this helped! qwq

M is -41. If you add 43 to -41, your result will be 2. A number line would help you, too.

Answer:

Question 10.

angle 1 = 137°

angle 2 = 43°

angle 3 = 137°

reasoning - vertically opposite angles are equal, and angles on a point total to 360 degrees

Question 11.

a) Vertical: I dont know sorry :(

b) Complementary: ∠c and ∠b

c) Suplementary: ∠c and ∠d

d) All adjacent: I dont know sorry :(

e) Find values of all angles, if angle c is 30°: ∠a = 90°, ∠b = 60°, ∠c = 30°, ∠d = 150°, ∠e = 30°

hope this helps :)

Answer:

i think its 200 m

Step-by-step explanation:

because 20 times 1000 rotations is 20000 cm so when u convert it to meter it is 200 meter if it is km it is 0.2 km

Answer:

how much km was left

Step-by-step explanation:

his whole journey length would be if u add both km

Answer:

0

Step-by-step explanation:

for which m is the slope, b is the y-intercept, x is any x value and y is any y value. By looking at the equation of the trend line, you can determine the y-intercept. For example, if the equation of the trend line is y=2x+5, the y-intercept is 5. You would receive this same answer if you let x = 0.

Answer:

27-degrees

Step-by-step explanation:

these are vertical angles which are equal to each other *congruent

39 + k = 66 --> *subtract 39 from both sides*

k = 27

Answer:

27°

Step-by-step explanation:

Remember the angle opposite of another angle in two straight lines are equal

So 66=39+k

Then put k by itself by subtracting 39 from both sides

66-39=k

k=27°

Answer:

the two balls are yellow and green, in either order.

Step-by-step explanation:

P(Y) = 5/10 = 1/2

P(R) = 3/10

P(G) = 2/10

Since the only combination that makes a product of 1/10, so

P(Y)*P(G) = (5//10) * (2/10) = 10/100 = 1/10

So the two balls are yellow and green, in either order.

Answer: y=2x+2

Step-by-step explanation:

Rule as an expression: 2x+11-8

Simplify: 2x+2

Rewrite as an equation with x (input) and y (output): y=2x+2

Answer:

5625π cm²

Step-by-step explanation:

Radius = 150 / 2 = 75 cm

Area = πr² = π(75)² = 5625π cm²

Answer: 17662.5 (I used 3.14 instead of the regular pi but if you need to use pi the answer would be 17671.4587)

Step-by-step explanation:

First, you grab the diameter then divide that by 2 (that gives you the radius of the circle) Then, multiple 75² * 3.14 (or pi) to give you the answer!

Hope this helps! Good luck!

interest is what the bank charges you to use their money and also when you receive (usually a percentage) of what you payed back!      ( hope this helps :) )\

Answer:

Step-by-step explanation:

4.

a)

P = 2width + 2length

8x = 2x + 2 length; 8x-2x = 2 length; 6x=2 length

length = 3x

b)

sides= 1/4 of 3x = 3x/4

perimeter of square = 4* side = 4*3x/4 = 3x

c)

x= 4

P rectangle =8x= 8*4= 32

P square = 3x = 3*4 = 12

32-12 = 20 cm greater is the P rectangle than P of square

d)

A rectangle = 2x*x = 2*4*4 = 32

A square =(3x/4)² = (3*4/4)² = 9

32-9 = 23 cm² greater is the A rectangle than A of square

5.

4Comic+1 Nonfiction

4comic = 8y so 1 comic = 2y

1 nonfiction = (3+7y)+ 2y

a)

1 nonfiction = 7y+2y+3 = 9y+3

b)

total= 8y+9y+3 = 17y+3

if y=4

total = 17*4 +3  = $71
