Step-by-step explanation:
step 1. what is the question? solve for x? okay.
step 2. 28/54 = (2x+ 8)/(5x - 4)
step 3. 28(5x - 4) = 54(2x + 8) (cross multiplication)
step 4. 14(5x - 4) = 27(2x + 8) (divide both sides by 2)
step 5. 70x - 56 = 54x + 216 (distributive property)
step 6. 16x = 272 (group x's and add 56 to both sides)
step 7. x = 17 (divide both sides by 16).
2x< -9 +1
2x< -8
x< - 8/2
x< - 4
3x> 2 - 5
3x > - 3
x> -3/3
x > -1
the third is the answer
Answer:
Area of green trapezoid would be:
(length of two parallel sides × h) ÷ 2
( 5cm x 2cm) ÷ 2
= 5 square centimetres
Area of the orange trapezoid would be:
(length of two parallel sides x h) ÷ 2
(10.5 cm × 3) ÷ 2
( 31. 5) ÷ 2
(15. 75 square centimetres
NOTE: h represents height
390-35=355
355-10w
355/10=35.5
355-10(35.5)
35 and a 1/2 weeks
36 weeks to have the full amount needed
Answer:
The scale factor is 1/2
Step-by-step explanation:
The coordinates of Point G are (4,6) and the coordinates of Point G' are (2,3). To get from 4 to 2 and 6 to 3, you have to multiply by 1/2. Therefore, the scale factor is 1/2.
