Answer:
-5.1, -5, -4.5, -4.45,-4 2/5
Answer:
x= 29/11 or y= 25/11
Step-by-step explanation:
2x - y= 3 ...........equation 1
x + 5y= 14 ............equation 2
Make x the subject of the formula in equation 2
x= 14 - 5y ..............equation 3
Substitute x=14 - 5y in equation 1
2(14- 5y) - y=3
28 - 10y - y=3
Collect like terms
-10y - y=3 - 28
-11y= -25
divide both sides by coefficient of y
-11y/-11 = -25/-11
y= 25/11
Substitute y= 25/11 in equation 3
x=14 - 5(25/11)
x= 14 - 125/11
x= 29/11
Answer:
x=5
Step-by-step explanation:
Since 32 is 8 times 4 cm, then 40/8=5.
Answer:
19/4 or 4.75
Step-by-step explanation:
Week 1: 1 1/8 = 1.125
Week 2: -2 5/8 = -2.625*
Week 3: 1 3/4 = 1.75
Week 4: -1 1/2 = -1.5
Week 5: 2 1/8 = 2.125*
2 1/8 - (-2 5/8) = 2.125 - (-2.625)
19/4 or 4.75
