Answer:

Let x = # of hours Sophia spends ironing shirts

Let y = # of hours London spends ironing shirts

Equations: x + y = 11 and 40x + 25y= 365

Step-by-step explanation:

If Sophia and London worked a combined 11 hours, then one of our equations is : x + y = 11

They also note that Sophia and London both ironed 365 shirts, and Sophia irons 40 shirts per hour while London can iron 25 shirts per hour. Our next equation is : 40x + 25y= 365

Answer:

Step-by-step explanation:

Since all the expressions are on a straight angle (equalling 180) combine the expressions to form on big expression that is equal to 180 and solve.

6x - 10 + 4x + 6 + 7x + 14 = 180

17x + 10 = 180

- 10 -10

17x = 170

Angles DEF and PQR are supplementary. Which is the value of x? (x-6) (2x+42) A 18 B. 48 C. 132 D. 42

Answers

Answer:

x = 48

Step-by-step explanation:

(x - 6)⁰ + ( 2x + 42)⁰ = 180⁰

x - 6⁰ + 2x + 42⁰ = 180⁰

x + 2x - 6⁰ + 42⁰ = 180⁰

3x + 36⁰ = 180⁰

3x + 36⁰ - 36⁰ = 180⁰ - 36⁰

3x = 144⁰

3x / 3 = 144⁰ / 3

x = 48

Hope this helps, thank you :) !!

The answer is x = 48

x=56

Step-by-step explanation:

because they are parallel lines, the angle 124 is the same measurement as the angle on the other side of the line with x. (look at the attachment, im bad at explaining with words lol)

then you do 180 - 124 (180 is the angle of a straight line) and you get x.

jackie made bracelets for 8 days. when he was done he had 96 bracelets. write and equation to express how many bracelets jackie made each day.

Answers

96 divided by 8.
Answers 12 bracelets per day

Answer:

12 bracelets.

Explanation:

If we assume Jackie made the same number of beaded bracelets each day, we can divide the total number of bracelets 96, by the amount of days it took to make all the bracelets, 8. This gives us

[tex]\frac{96}{8}[/tex]=12

We can check the answer by working backwards. Each day 12 bracelets were made. There were 8 days. 12 × 8 = 96 . So for 8 days 12 bracelets were made giving Jackie 96 bracelets.

A trapezoid was broken into a triangle and rectangle.

The area of the rectangle is cm2.
The area of the triangle is cm2.
The area of the trapezoid is cm2.

Answers

Answer:

Step-by-step explanation:

Base x Height = Area

10x12=120 the area of the rectangle is 120

area of the triangle is 28

sorry but I don't know the trapezoid

The area of the rectangle is 120 cm².

The area of the triangle is 24 cm².

The area of the trapezoid is 144 cm².

What is a trapezoid?

An open, flat object with four straight sides and one pair of parallel sides is referred to as a trapezoid or trapezium.

A trapezium's non-parallel sides are referred to as the legs, while its parallel sides are referred to as the bases. The legs of a trapezium can also be parallel. The parallel sides may be vertical, horizontal, or angled.

The area of a trapezoid is (1/2)×(sum of the two parallel sides)×height.

We know, the area of a triangle is (1/2)×base×height and the area of a rectangle is (length×width).

Therefore, From the given information,

The area of the triangle is, (1/2)×4×12 = 24cm².

And the area of the rectangle is, (10×12) = 120 cm².

Therefore, The area of the trapezoid is,

= (24 + 120) cm².

= 144 cm².
