What's is the value of y in the equation 5x + 2y =20 when x=0.3

To solve this problem, we must substitute in the value we are given for x into the equation and then solve the equation for the variable y. To begin, we substitute in the value and perform the multiplication with the coefficient, as follows:

5(0.3) + 2y = 20

1.5 +2y = 20

Next, we must subtract 1.5 from both sides to get the variable term by itself. If we do this, then we get:

2y = 18.5

Finally, we must divide both sides by 2y to cancel out the coefficient of 2 on the variable y. Therefore your answer is:

y = 9.25

Hope this helps!

cut 138 centimeters off

step-by-step explanation:

250-112 = 138

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
