Answer:
n=6
j=15
u=7.6
Step-by-step explanation:
Given TACBRD=MYPXEF
we find that the ratio is 1 : 2.5 and we solve from here
The sum of 14 and a number is 14+x
we know that this equals 17, so: 14+x=17.
Let's substract 14 from both sides:
x=17-14
x=3
so the number is 3.
Answer:
Cost of chip cookies = $17.5
Cost of ginger cookies = $19.5
Step-by-step explanation:
Assume;
Cost of chip cookies = c
Cost of ginger cookies = g
So,
Maya's sales = 8c + 12g = 374
.....Eq1
Carlo's sales = 2c + 4g = 113
.......Eq2
4 x eq2
So
8c + 16g = 452......Eq3
Eq 3 - Eq 1
4g = 78
g = 19.5
and
c = 17.5
Cost of chip cookies = $17.5
Cost of ginger cookies = $19.5
The school club needs additional 43.25 feet of rope.
<u>Step-by-step explanation</u>:
Rope containing 2 pieces have 16 yards in length.
Rope containing 1 piece have 12.5 yards in length.
Rope containing 1 piece have 123.25 feet in length.
We will need this conversion formula:
1 yard = 3 foot.
Now let us find dimensions of each part.
Rope containing 2 pieces having 16 yards in length = 2 16
= 32 yards
= 32 3
= 96 feet.
Rope containing 1 piece having 12.5 yards in length or 37.5 feet.
Rope containing 1 piece having 123.25 feet in length.
Adding the three measures = 96 + 37.5 +123.25
= 256.75 feet.
Rope required = 300 - 256.75
= 43.25 feet.
