The sum of three consecutive odd integers is fifty-one. Find the integers. (Enter your answers as a comma-separated list.)
Answer:
15, 17, 19
Step-by-step explanation:
let the first odd number be n then the next 2 are n + 2 and n + 4 , then
n + n + 2 + n + 4 = 51
3n + 6 = 51 ( subtract 6 from both sides )
3n = 45 ( divide both sides by 3 )
n = 15
Then
n + 2 = 17 and n + 4 = 19
The 3 consecutive odd numbers are 15, 17, 19
A price used to be £40, but is now £50.
What is the percentage increase?
Answer:
25%
Step-by-step explanation:
MP= 40

Answer:
-40m = 59.2
Step-by-step explanation:
simplify
Answer:
-40m + 59.2
Step-by-step explanation:
Distribute
-40m + 59.2
If you're solving for m then set the equation equal to 0 and solve.
-40m + 59.2 = 0
-40m = -59.2
m = 37/25

Jocelyn estimates that a piece of wood measures 5.5cm. If it actually measures 5.62 cm, what is the percent error of Jocelyn’s estimate?
Answer:
2.14% error
Step-by-step explanation:
Use the percent error formula:
| (observed - expected) / expected | x 100
Plug in the observed and expected values:
| (observed - expected) / expected | x 100
| (5.5 - 5.62) / 5.62 | x 100
Calculate:
= 2.14% error
So, the percent error of Jocelyn's estimate is 2.14%
50% of 50% of x. PLEASE HELP I WILL GIVE BRAINLIEST
Answer:
25. 50 percent of 50 is 25 divided by 2.
Step-by-step explanation:
step1:Our output value is .50.
step2:we represent the unknown value with x
step3: from step1 above,.50=100%
step4: similarly,x=50%
step5: This results in a pair of simple equation:
.50=100%(1)
x=50%(2)
step6:by dividing equation 1 by equation 2 and noting that both the RHS(right hand side)of both equations have the same unite(%);we have
.50. 100%
____. = ____
x. 50%
step7: again,the reciprocal of both sides gives
x. 50
___ =. ___
50. 100
°x=0.25
therefore,50%of.50 is 0.25

Aubrey finished 2/9 of a project on Monday and 1/4 of the project of Tuesday. How much of the project has Aubrey completed?
Answer:
17/36
Step-by-step explanation:
We have to find a common denominator, so the first common denominator for 4 and 9 is 36. 9x4=36, so we multiply 2 by 4, which equals 8. 4x9-36, so we multiply the 1 by 9, and get 9. Then we add the numerators, 8 and 9, and get 17. So it's 17/36
Sasha uses 6.1 pints of white paint and blue paint to paint her bedroom walls. 2/5 of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls?
Answer: 3.66 pints of blue paint.
Step-by-step explanation:
She used 2/5 of the total number of pints to paint white.
That number in pints is:
= 2/5 * 6.1
= 2.44 pints of white
The number of pints used to paint blue is therefore:
= 6.1 - 2.44
= 3.66 pints of blue paint.

In one day, Ricardo hiked 2_ 2 3 times as far as Bernie and Chloe hiked before they ate lunch. How far did he hike?
Complete question :
Bernie and Chloe hiked the Tremont Trail to the end and back. Then they hiked the Wildflower trail to the end before stopping to eat lunch. Before Ricardo ate his lunch, he hiked 2 2/3 times as far as Bernie and Chloe. How far did he hike?
Required diagram is attached below
Answer:
25 miles
Step-by-step explanation:
Tremont Trail = 3 1/2 miles
Wildflower trail = 2 3/8 miles
Distance covered ; Tremont Trail and back : (3 1/2 * 2). = 7/2 * 2 = 14 /2 = 7 miles
Total distance covered by Bernie and Chloe before stopping for lunch /
(7 miles + 2 3/8 Miles) = 9 3/8 miles = 75/8 miles
Ricardo's distance = 2 2/3 * Bernie and Chloe's total distance
Ricardo's distance = 8/3 * 75/8 = 600 /24 = 25 miles

2
− 3
Step-by-step explanation:
let f(X)=x^2+2 and g(X)=1-3x
Answer:
1. y = x2+2
2. g = (-3x+1)/x
Step-by-step explanation:
1. No explanation
2.
Let's solve for g.
gx=1−3x
Step 1: Divide both sides by x
gx /x = −(3x+1 )/x
g = (-3x+1)/x

0.2(3k+1)=-0.4-(-0.2-0.1K)
Answer:
k=−0.8
Step-by-step explanation:
Start with the equation: 0.2(3k+1)=-0.4-(-0.2-0.1K)
Use distributive property on each side of the equation. For the left side, distribute 0.2 into 3k and 1, and for the right side, distribute -1 into -0.2 and -0.1k. (We use a -1 because the negative sign on the outside of the parenthesis is equivalent to -1)
(0.2)(3k) + (0.2)(1) = 0.6k + 0.2
(-1)(-0.2) + (-1)(-0.1k) = 0.2 + 0.1k
New equation: 0.6k + 0.2 = -0.4 + 0.2 + 0.1k
Now we can combine like terms on the right side. (-0.4 and 0.2)
0.6k + 0.2 = 0.1k - 0.2
Now to get rid of k on one side, we can subtract 0.1k from the right side.
(0.6k - 0.1k) + 0.2 = (0.1k - 0.1k) - 0.2
0.5k + 0.2 = -0.2
Now we need to get 0.5k by itself, so we'll subtract the 0.2 on both sides.
0.5k + (0.2 - 0.2) = (-0.2 - 0.2)
0.5k = -0.4
To get k by itself, we must divide both sides by 0.5.
(0.5k / 0.5) = (-0.4 / 0.5)
k = -0.8
