Mathematics
1 answer:
ANEK [815]4 years ago
6 0

Answer:

x = 13

Step-by-step explanation:

5x + 25 must equal 7x - 1, because all of the angles in the figure are right angles.

Then 5x + 25 = 7x - 1, and

                  25 = 2x - 1, and so 2x = 26 and x = 13

List the measurement below from smallest to largest .7 cm 18 mm 1 m 3 dm
Ivanshal [37]
In order to list the measurements from smallest to largest, we convert all the measurement to a common unit. In this item, we convert the given to meters, m.

A. The conversion factor to be used here is 1 m = 100 cm
      (7 cm)(1 m / 100 cm) = 0.07 m

B. Conversion factor: 1 m = 1000 mm
     (18 mm) (1 m / 1000 mm) = 0.018 m

C. Let us list this as is, 1 m

D. The conversion factor here is 1 m = 10 dm
    (3 dm)(1 m / 10 dm) = 0.3 m

By the converted values, we are then able to arrange the given measurements.Hence, the arrangement should be 18 mm, 7 cm, 3 dm, and 1 m.

lapo4ka [179]

Answer:

The number of candies Hayley  has is  16 .

Step-by-step explanation:

The number of candies Hayley has = x

So, Number of candies Hayden has = (x + 3)

Then the Number of candies i have = 2(x + 3)

Also,according to the question:

2(x + 3) = 38

or, 2x + 6 = 38 ⇒    2x = 32

or, x = 32/2 = 16

⇒  x = 16

So, the number of candies Hayley  has is  x = 16 .
