Answer:
x= -2
Step-by-step explanation:
suppose,
the number is x
so,
Four more than 6 times a number = 6.x+4=6x+4
9 times the number increased by 10 =9x+10
Now,
6x+4 = 9x+10
⇒9x-6x=4-10
⇒3x=-6
⇒x=- 6/3 [divide both sides by 3 ]
⇒x= -2

Answer:
Natasha can wrap 128 gifts in total
Step-by-step explanation:
Let us use the ratio method to solve the question
∵ Natasha has 240 square feet of wrapping paper
∵ Natasha can wrap 8 gifts with 15 square feet
→ By using the ratio method
→ Gift : square feet
→ 8 : 15
→ x : 240
→ By using cross multiplication
∵ x × 15 = 8 × 240
∴ 15x = 1920
→ Divide both sides by 15
∵ x = 128
∵ x represents the number of gifts
∴ Natasha can wrap 128 gifts in total
