Answer:

-26z - 15

Step-by-step explanation:

tp simplify an expression, you combine all the things with z in them and all the plain numbers. In this case you have a negative 20z and a negative 6 z, which makes negative 26z. The only number is -15 so there's nothing to combine with that. Put the pieces together and you have -26z-15

A length of string that is 240 cm long is cut into three pieces the second piece is 25% longer than the first piece the third pi

Tresset [83]

Hey there,
Let's say that the first piece is x cm
1st = x
2nd = x + 25%
3rd = x - 25%
100% = 240 cm
1% = 240 / 100
= 2.4cm
x + x + 25 + x - 25 = 100
3x + 25 - 25 = 100
3x = 100 - 25 + 25
3x = 100
3x = 240 cm
x = 240 / 3
= 80 cm
1st piece = 80 cm
2nd piece = 80 + (25% x 80)
= 80 + 20
= 100cm
3rd piece = 80 cm - (25% x 80)
= 80 cm - 20
= 60cm

Hope this helps :))

I answered the rest of my questions but this one is confusing me

Gwar [14]

Answer:

the answer is 36ft by 48ft

Step-by-step explanation:

We first need to find the measurements of the green squares. Given the drawing is to scale we can say that each green square has equivalent measurements. Since there are 144 feet on each side of the original drawing, and 12 green squares on each side as well, then we need to divide 144 by 12 to find the measurements of one square. 144/12=12. the green squares are each 12ft by 12ft. to find the measurement of the jungle gym, we see how many green squares are on each side (there are 3 and 4) then multiply that number by 12. 4*12 I 48, and 3*12 is 36. Hence the measurements of 36ft by 48ft.
