9. - 20  2/9

10. 82575 (multiplying)

Step-by-step explanation:

1.34+914=____221_____________

948 =  221+ 727     (subtracting 221 from 948)

2. 16+34=______45___________

50=  45+5    ( adding 5 to 45 to get 50)

3. 46+418=_________220________

464= 220+ 244    ( subtracting 220 from 464)

4. 45-615=2 ________________

- 570 = 2( -285)   (dividing -570 by 2)

5. 25-36=_________________ (-9)

-9 = -9   ( subtraction)

6. 37 x 45=_________________ 1665  (multiplying)

7. 58x (-53)=_________________ -3074 (multiplying)

8. 3425=_________________ 685 *5  (dividing by 5)

9. 910÷(-45)=_________________ 182/ (-9) (dividing both by 5)

= - 20  2/9

10. 367 x 225=_________________ 82575 (multiplying)

Answer:

32%

Step-by-step explanation:

All you have to do is divide the numerator by the denominator and then multiply that result with 100

Answer:

Step-by-step explanation:

Complementary angles are two angles that add up to be 90 degrees.

We can write an equation and solve for x.

(3x - 4) + (5x + 6) = 90

~Combine like terms

8x + 2 = 90

~Subtract 2 to both sides

8x = 88

~Divide 8 to both sides

x = 11

Angle DEF:

3x − 4

3(11) - 4

33 - 4

29°

Angle FEG:

5x + 6

5(11) + 6

55 + 6

61°

Check:

29 + 61 = 90°

Best of Luck!

Answer:

7250

Step-by-step explanation:

This is like the pythagorean theorem. So you add A^2,B^2, and C^2. So 25^2 + 60^2 + 55^2. 625 + 3600 + 3025. That equals to 7250.

Answer:

she needs 3 packages

Step-by-step explanation:

the total area of the cd is 27 cm

so like

she needs to wrap 27 cm of area

because 0.5 cm by 14 cm by 12.5 cm added all together is 27

then

27 cm equals 10.6 inches

so now we need to find how many 300cm2 will fit into that 11 inch space

There are 0.00107639 square feet in a square centimeter.

but we want to know how many feet not square feet

0.00107639 × 27 =

0.02906253

2.906253

there are 2.906253 feet per suare foot

so 2.9 rounded up is 3

she needs 3 packages

Answer:

39% of 198 = 77.22

Have a nice day.

1: Calculate the percentage of a number.

For example: 39% of 198 = 77.22

2: Calculate a percentage based on 2 numbers.

For example: 77.22/198 = 39%

hope this help!

Step-by-step explanation:

Answer:

-29, -3.17, 153

Step-by-step explanation:

in order from least to greatest this is the list.

-29 is the number farthest below zero, and 153 is the number farthest above zero.

Step-by-step explanation:

x = -4, 1/2 is the value of x

The values of x that satisfy the equation (2x - 1)(x + 4) = 0 are

x = 1/2 and x = -4.

Here, we have,

To solve for the values of x in the equation (2x - 1)(x + 4) = 0, we can use the zero-product property, which states that if the product of two factors is equal to zero, then at least one of the factors must be zero.

So, we set each factor equal to zero and solve for x:

2x - 1 = 0

Adding 1 to both sides:

2x = 1

Dividing both sides by 2:

x = 1/2

x + 4 = 0

Subtracting 4 from both sides:

x = -4

Therefore, the values of x that satisfy the equation (2x - 1)(x + 4) = 0 are x = 1/2 and x = -4.

Answer:

No solution

Step-by-step explanation:

Any equations with the same slope are parallel, or will never intersect.

In a slope-intercept equation, this would mean the 'm' values are the same.

y = mx + b

Two equations:

y = 5x - 4

y = 5x - 5

Since the two equations given have the same slope, they will never intercept and therefore have no solution.

Answer:

37 degrees

Step-by-step explanation:

All insides of triangles = 180 degrees, so...

67 degrees + 76 degrees + (x + 48) degrees = 180

67 + 76 + (x + 48) = 180

143 + x + 48 = 180

191 + x = 180

x = -11

x + 48

-11 + 48

37 degrees
