Answer:

1/3a - 8

Step-by-step explanation:

Distribute negative sign:

2/3a - 5 + -1 (1/3a + 3)

2/3a + -5 + -1 (1/3a) + (-1)(3)

2/3a + -5 + -1/3a + -3

Combine like terms:

2/3a + -5 + -1/3a + -3

(2/3a + -1/3a) + (-5 + -3)

= 1/3a - 8

Answer:

The values of x and y are x = 6 and y = 9Step-by-step explanation:

MNOP is a parallelogram its diagonal MO and PN intersected at point A

In any parallelogram diagonals:

Bisect each other

Meet each other at their mid-point

In parallelogram MNOP

∵ MO and NP are its diagonal

∵ MO intersect NP at point A

- Point A is the mid-point pf them

∴ MO and NP bisect each other

∴ MA = AO

∴ PA = AN

∵ MA = x + 5

∵ AO = y + 2

- Equate them

∴ x + 5 = y + 2 ⇒ (1)

∵ PA = 3x

∵ AN = 2y

- Equate them

∴ 2y = 3x

- Divide both sides by 2

∴ y = 1.5x ⇒ (2)

Now we have a system of equations to solve it

Substitute y in equation (1) by equation (2)

∴ x + 5 = 1.5x + 2

- Subtract 1.5x from both sides

∴ - 0.5x + 5 = 2

- Subtract 5 from both sides

∴ - 0.5x = -3

- Divide both sides by - 0.5

∴ x = 6

- Substitute the value of x in equation (2) to find y

∵ y = 1.5(6)

∴ y = 9

The values of x and y are x = 6 and y = 9

Explanation:

On the third line is where the student went from -12-3 to -9. This is not correct. Instead, it should be -12-3 turning into -15.

Think of it like being 12 feet under water (the number -12) and then moving 3 more feet deeper under water. You'll move down 3 to get to -15 to represent being 15 feet under water. Use a vertical number line if needed.

You can also compute -12-3 like 12+3 = 15, then just make everything negative. So -12-3 = -15

Answer:

∡a has a vertical angle sibling of 40°, and vertical angles are always congruent.

∡b is the 3rd angle in a triangle, the other two are 40° and 90°, recall all interior angles in a triangle add up to 180°.

∡c is a linear angle, namely an angle on the same flat-line as another, and linear angles always add up to 180°.

Step-by-step explanation:

Putting y=-3 in second equation

[tex]\\ \sf\longmapsto x-(-3)=8[/tex]

[tex]\\ \sf\longmapsto x+3=8[/tex]

[tex]\\ \sf\longmapsto x=8-3[/tex]

[tex]\\ \sf\longmapsto x=5[/tex]

Divide the option with 4 so that you can get the equivalent ratio to 5:9 .

The number in the problem whose result is 40, will be 3,600 and 90.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

Division means the separation of something into different parts, sharing of something among different people, places, etc.

Use the digits nine, six, and three one time each in the following Multi-digit division problem then rewrite the problem.

Then the problem whose result is 40 will be given as the division of 3600 by 90.

3,600 / 90 = 40

The number in the problem whose result is 40, will be 3,600 and 90.

Answer:

Total Area = 235cm^2

Step-by-step explanation:

Step 1 ) we have our lengths 11 and 20 so we need to separate the into 2 shapes  Step 2)   Label and draw new shape 20-11 = 9  to show (Shape square  1) = measuring 9 *9 and   another  (Shape Rectangle 2) = 11* 14  Step 3) Show how you do the multiplication of Square shape 9* 9 = 81cm^2  and Area Rectangle 11 * 14 = 154 cm^2   Total Area = 81+154 = 235cm^2    You can if you like in table multiplication show 11*14 by adding a zero underneath the 14 = 140 +14 = 154 then add and show +81 = 235cm^2 It is always easier to retain a shape if subtracting to get a 2nd shape this way it saves time with subtraction and in my example only needed to subtract 20-11 = 9 then 9*9 = 81cm^2 to retain the 14 *11 = 154cm^2 area for the rectangle

Answer:

Answer:

252, 1 1/4, 308, 1 1/2

Step-by-step explanation:

5. The kitchen is 2 1/4 in by 1 3/4 in. 2 1/4in = 9/4in = 18ft. 1 3/4in = 7/4in = 14ft.

So we have 18ft by 14ft. The area is one side multiplied by the other side:

18 × 14 = 252ft^2.

6. 10/2 = 5. 5/4 in = 1 1/4in.

7. Bedroom 2 is 1 3/4in by 2 3/4in. 1 3/4in = 7/4in = 14ft. 2 3/4in = 11/4in = 22ft.

14ft × 22ft = 308ft^2 of carpet.

8. 12ft/2 = 6. 6/4 = 1 2/4 = 1 1/2 in.

Answer in the picture.

Answer:

To determine if the difference of two numbers is less or greater than the first number, check the value of the first number, and the value of the second number.

(greater) - (lesser) = (positive)

(lesser) - (greater) = (negative)

(neg lesser) - (neg greater) = (positive)

(neg greater) - (neg lesser) = (negative)

For Example:

10 - 5 = 5

5 - 10 = -5

(-5) - (-10) = 5

(-10) - (-5) = -5

The charity should collect 600 cans of food

Number of families that the charity asked to donate food = 150

80% of the families donated 5 cans of food

Number of families that actually donated 5 cans of food = (80/100) x 150

Number of families that actually donated 5 cans of food = 0.8 x 150

Number of families that actually donated 5 cans of food  = 120

Number of cans donated by each family = 5

Number of cans donated by 120 families = 5 x 120

Number of cans donated by 120 families = 600
