Answer: B) $21

Step-by-step explanation:

Given : Sean spent $38 for shorts.

This was $4 less than twice what he spent for a shirt.

Let x denotes the cost of shirt.

The equation 2x-4 = 38 is set to find the cost of the shirt (x).

To solve the above equation for x , first we add4 on both the sides , we get

2x=42

Divide both sides by 2  , we get

x=21

Thus , the cos of shirt = $21

Hence, Sean spent $21 on the shirt.

∴ The correct option is B) $21

Somebody help me !!!! HELPP please!!!

Step 1: Read and understand the problem statement.

You are given (time, depth) pairs of (20 s, 8 cm) and (40 s, 0 cm) and asked to write an equation that describes the relationship of depth (y) to time (x).

The rate of change is (0 cm -8 cm)/(40 s -20 s) = -8 cm/(20 s) = -2/5 cm/s. Then in point-slope form using the second point, the linear function rule is
  y = (-2/5)(x -40) +0
You can expand this to
  y = (-2/5)x +16
  y = -0.4x +16 . . . . . . using a decimal number for the slope

_____
If the bathtubs in your "draining race" start with the same level, the one with the steepest slope (-0.5 cm/s) will win.

❗️HELP ASAP❗️
tangare [24]
I think the answer is G.

I think this because of the fact families (like my elementary teacher used to say)
It’s like about multiplication of fact families so make it where it would have fact families with those numbers as the sums.
I hope this helps! Be safe out there.

You may solve this ratio by cross multiplying. To do this, you multiply the numbers diagonally across from each other.

    x/10 = 1/5
    10(1) = x(5)
        10 = 5x
          2 = x

Answer:
x = 2

1. Carter bought 3 oxen, 4 cows and 6 calves for $260. He paid twice as much for a cow as for a calf
valentinak56 [21]

Answer:

120 for oxen, 80 for cows, 60 for calves

o = 2x

Step-by-step explanation:

3o + 4x + 6c = 260

x = 2c

o = 2x

6x + 4x + 3x = 260

13x = 260

260 / 13 = 20

3o = 6x = 120

4x = 80

6c = 3x = 60

o = 2x
