Answer:
14 1/30
Step-by-step explanation:
convert the fractions so that the LCF is the denominator
1/5---->6/30
5/6----->25/30
5 6/30+8 25/30
13 31/30
14 1/30
Answer:
B
Step-by-step explanation:
Answer is 7
Step by step explanation
|-7|=7
Answer:
17:7
Step-by-step explanation:
The first jar is 2/3 water, and the second jar is 3/4 water. Since the jars are equal volume, the resulting mixture will be the average.
(2/3 + 3/4) / 2
(8/12 + 9/12) / 2
(17/12) / 2
17/24
If the jar is divided into 24 parts, 17 parts are water, and the remaining 7 parts are vinegar. So the ratio is 17:7.
Answer:
x=-6/29
y=-17/29
Step-by-step explanation:
we have the system of equations
-13x+8y=-2 ------> equation 1
2x+y=-1 ------> equation 2
Solve by elimination
step 1
Multiply equation 2 by -8 on both sides
-8[2x+y=-1 ] ---------> -16x-8y=8 ------> equation 3
step 2
Adds equation 1 and equation 3
-13x+8y=-2
-16x-8y=8
-----------------
-29x=6
x=-6/29
Find out the value of y
substitute the value of x in any equation
2x+y=-1
2(-6/29)+y=-1
-12/29+y=-1
y=-1+(12/29)
y=-17/29
therefore
The answer is
x=-6/29
y=-17/29
