Answer:
y = 
Step-by-step explanation:
Given
x = 2y - 3 ( add 3 to both sides )
x + 3 = 2y ( divide both sides by 2 )
= y
Answer:
3
Step-by-step explanation: y=10-x so 3x-2=10-x 4x=12 x=3
we have
4 yards 24 inches wide
6 yards long
<u>step 1</u>
convert inches to yards
we know that
1 yard is equal to 36 inches
so
24 inches=(24/36)=2/3 yards
so
4 yards 24 inches wide=4+(2/3)=14/3 yards
step 2
Find the ratio
W/L=(14/3)/(6)=14/18=7/9
therefore
<u>the answer is </u>
the ratio is equal to (7/9)
Answer:
a. 4 : 1
b. 2 students
c. 3 : 1
Step-by-step explanation:
a. There were 12 students who got a C and 3 students who got As. The ratio is therefore:
12 : 3
Take it to the lowest form by dividing both sides by 3:
= 4 : 1
b. There were 4 students with a D grade and 8 with a B. The ratio is:
= 4 : 8
Taken to the lowest form that would be:
= 1 : 2
This means that for every student receiving a D, 2 students received an A.
c. 12 students received a C and 4 students received a D. That ratio is therefore:
= 12 : 4
Take to the lowest form by dividing both sides by 4:
= 3 : 1
Answer:
B.
