The second of two numbers is 4 times the first. their sum is 50. find the numbers
Sphinxa [80]

Answer:

The first number is 10, and the second is 40.

Step-by-step explanation:

X is equivalent to 10, and the equation for this question is x + 4x = 50. Therefore, 5x = 50. If you divide both sides by 5, you get x = 10. This means the first number is 10, and since the second is 4 times that, 4*10 = 40. 40 + 10 = 50, to check.

5. Find JK to the nearest whole number.<br> A
pentagon [3]

Answer:

JK ≈ 63 units

Step-by-step explanation:

Using the sine ratio in the right triangle

sin44° = \frac{opposite}{hypotenuse} = \frac{JK}{JL} = \frac{JK}{90} ( multiply both sides by 90 )

90 × sin44° = JK , that is

JK ≈ 63 ( to the nearest whole number )
