Answer : x=3
Step-by-step explanation:
Explanation:
2x+3=9
We want to find the variable x, so we have to make it alone. To do so, first subtract 3 from both sides of the equation:
2x+3 − 3=9 − 3
2x=6
Now divide both sides by 2:
2x2=62
So the final answer is:
x=3
1 pack of 12 will give 4 students their pencils. 20/4 = 5
Answer:
Then it is just a matter of plugging in the values into the formula. For example, if one base is 6 cm long, the other is 10 cm long and the height is 4 cm, the area is then (6 + 10) / 2 x 4 = 16 / 2 x 4 = 8 x 4 = 32 cm 2 (32 square centimeters).
Step-by-step explanation:
Answer:
150
Step-by-step explanation:
Y = 1.3x
point C : (3,?)...so we sub in 3 for x and solve for y
y = 1.3(3)
y = 3.9
so point C is (3,3.9)
point D : (-6,?)...so we sub in -6 for x and solve for y
y = 1.3(-6)
y = -7.8
so point D is (-6,-7.8)
