Does anyone know this?

35 cm, 45 cm, 50 cm

Step-by-step explanation:

Sum the parts of the ratio, 7 + 9 + 10 = 26 parts

Divide 130 cm by 26 to find the value of one part of the ratio

130 cm ÷ 26 = 5 cm ← value of 1 part of the ratio, thus

7 parts = 7 × 5 cm = 35 cm

9 parts = 9 × 5 cm = 45 cm

10 parts = 10 × 5 cm = 50 cm

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
