For number 7 the answer should be 20%. 10 is 50% and the other 6 is 30%.
Answer:
5x = 14
Step-by-step explanation:
If 5 yards of fabric is $14 you need an equation that would solve how much 1 yard of fabric costs. You can say 5x = 14 or x = 2.8 which means that one yard of fabric (1x or just x) is $2.80.
13x = 39 can replace 3x + 5y = 59 in the original system and still produce the same solution.
Answer:
x= 7/5 (1 2/5 or 1.4)
Step-by-step explanation:
Move the variable to the left-hand side and change its sign.
12x-15+3x=6
Move the constant to the right-hand side and change its sign.
12x+3x=6+15
Collect like terms.
15x=21
Divide both sides of the equation by 15.
x=7/5 (1 2/5 or 1.4)
A quadrilateral is a shape with four sides
We have two parallel sides with length 7cm and another two parallel sides with length 4cm
Four right angles
The shape is a rectangle
