Answer:
Step-by-step explanation:
x + y = 40
x>y
(11/2)y - (13/4)*x = - 25
x = 40 - y
(11/2)y - (13/4)(40-y) = - 25 multiply by 4
22y - 13( 40 - y) = - 100
22y - 520 + 13y = -400 Add 520
35y = 120
y = 120 / 35
y = 3 3/7
x = 40 - y
x = 36 4/7
Is it -2123 that is my answer
Answer:
B. Less than a day
Step-by-step explanation:
From the question, the circuit board manufacturer produces 2000 board per hour.
Let x be the number of hours it will take to produce 16500 boards .
That’s
2000 boards = 1 hour
16500 boards = x hour
Cross multiply
xhour x 2000 = 1 x 16500
x hour = 16500/2000
x hour = 8.25 hours
8.25 hours is less than a day

in simplest form:
First, find the greatest common factor (GCF) of 12, 15.
Factors of 12: 1, 2, 3, 4, 6, 12
Factors of 15: 1, 3, 5, 15
The GCF is 3.
Second, divide the numerator (12) by the GCF. / Your problem should look like: 12 ÷ 3 = 4
Third, divide the denominator (15) by the GCF. / Your problem should look like: 15 ÷ 3 = 5
Fourth, rewrite the fraction in the simplified form. / Your problem should look like:
