What is the value of t? :O (A) -20 (B) -5 (C) 5 (D) 20

1 answer:

3 0

3/5t -4 -7/10t = -2 (as you know 3/5 = 6/10) so
6/10t - 4 - 7/10t = -2
Simplify
-1/10t -4 = -2
add 4 to both sides
-1/10t - 4 + 4 = -2 + 4
-1/10t = 2
multiply -10 to both sides
-1/10t *(-10) = 2 * (-10)
Simplify
t = -20

Answer first one t = -20

What is the value of X? (geometry, right triangles)

Dahasolnce [82]

Answer:

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin30° = $\frac{1}{2}$ , then

sin30° = $\frac{opposite}{hypotenuse}$ = $\frac{x}{10}$ = $\frac{1}{2}$ ( cross- multiply )

2x = 10 ( divide both sides by 2 )

x = 5 → C

Isandro and Yvette each have a calculator. Yvette starts at 100 and subtracts 7 each time. Isandro starts at 0 and adds 3 each t

Talja [164]

Answer: 30

Step-by-step explanation:

Yvette- 100-7

Isandro- 0+3

1.) I'm going to speed up the process and multiply by 5.

Yvette: 100-7

7 × 5 = 35

100-35= 65

65-35= 30

Isandro: 0+3

3 × 5 = 15

0+15= 15

15+15= 30

2.) If they keep going on this pattern they will have the same number on the 10 round.

rachel bought 1 3/5 pounds of peaches for $.60 and 3 1/2 pounds of apples for $1.75. which fruit costs more per pound ? explain

babunello [35]

The peaches cost more per pound because if you divide the pounds of peaches by the cost, it's more than the cost per pound of apples.
