Answer:
The equation is a contradiction: it has no solutions
Step-by-step explanation:
5(+2)−6(2−)=+10(+1)
5(x+2)−6(2−x)=x+10(x+1)5(x+2)-6(2-x)=x+10(x+1)5(x+2)−6(2−x)=x+10(x+1)
Solve
Distribute
5(+2)−6(2−)=+10(+1)
5+10−6(2−)=+10(+1)
Rearrange terms
Distribute
Subtract the numbers
Combine like terms
Distribute
Combine like terms
Add
2 to both sides of the equation
Simplify
Subtract 11 from both sides of the equation
Simplify
Result
0=12
Answer:
x = -11 (sorry if this is wrong)
Step-by-step explanation:
5(x+2)-6(2-x)=10(x+1)
5x +10 -12x + 6x = 10x + 10
-1x + 10 = 10x + 10
-10x -10x
-11x + 10 = 10
-10 -10
-11x = 0
---- ----

Find the value of x.
56°
57°
85
2x
4x
Answer:
56
Step-by-step explanation:
Simplifying
x + 7x = 56 + 8
Combine like terms: x + 7x = 8x
8x = 56 + 8
Combine like terms: 56 + 8 = 64
8x = 64
Solving
8x = 64
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '8'.
x = 8
Simplifying
x = 8

Answer: 2 ribbons can be cut
Since 3/4 divided by 1/3 = 2.25, therefore you can make 2 full sized ribbons. He will have 3/4 of a ribbon left.
The diameter of the wheel of a unicycle is 0.7m. Elaine tries to ride the unicycle and manages to go in a straight line for 32 full revolutions before falling off. How far did Elaine manage to cycle in metres? Give your answer rounded to 1 DP.
Answer:
70.4metres
Step-by-step explanation:
Wheel Diameter = 0.7m
Wheel Radius; 0.7m / 2 = 0.35m
For one rotation of the wheel, the distance travelled = circumference of the wheel.
Circumference = 2 x pi x radius
= 2 × π × r
= 2 × π × 0.35
= 2.1991148575 m
Elaine tries to ride the unicycle and manages to go in a straight line for 32 full revolutions
Distance travelled with 32 full revolutions of the wheel = 32 x 2.1991148575 m =
Distance in meters = 70.37167544m
Approximately = 70.4m
Therefore, Elaine managed to cycle 70.4metres

Step-by-step explanation:
Delia went to the market to buy 4 pounds of sliced fruit in a container. She paid with a $20 bill and a $5 bill and received $3.67 as change. She paid $1.29 in taxes for the fruit. What was the cost for one pound of sliced fruit before taxes?
Answer:
$4.57. Hope this helps :)
Step-by-step explanation:
20+5=25
then you do
25-3.67= $21.33
you then divide that by the number of pounds she bought.
21.33/4= 5.3325
round that to the hundreths place and you get $5.33
so she paid $5.33 for a pound
Answer:
$4.74 per pound
Step-by-step explanation:
((20 + 5) – 3.67) / 4.5 = (25 – 3.67) / 4.5 =
(21.33) / 4.5 = 4.74
_______________________________
I've seen this same problem before, it should be 4.5 pounds.
The stock of Company A lost $1.18 throughout the day and ended at a value of
$28.32. By what percentage did the stock decline?
Answer:
the percentage did the stock decline is 4%
Step-by-step explanation:
The computation of the percentage did the stock decline as follows:
= Lost value ÷ original price
= $1.18 ÷ ($1.18 + $28.32)
= $1.18 ÷ $29.50
= 4% decline
Hence, the percentage did the stock decline is 4%

Solve algebraically the simultaneous equations
y = 2x2 – 3x - 10
2x - y = -2
Answer:
(-3/2, -1) and (4, 10)
Step-by-step explanation:
Given the simultaneous equations
y = 2x^2 – 3x - 10 ... 1
2x - y = -2 .... 2
From equation2;
-y = -2-2x
y = 2x+2 ..... 3
Substitute 3 into 1
Recall y = 2x^2 – 3x - 10
2x+2 = 2x^2 – 3x - 10
Collect like terms
2x^2 – 3x - 10 - 2x -2 = 0
2x^2 – 5x - 12 = 0
2x^2 – 8x+3x - 12 = 0
2x(x-4)+3(x-4) = 0
(2x+3)(x-4) = 0
2x+3 = 0 and x-4 = 0
2x = -3 and x = 4
x = -3/2 and x = 4
Recall that
y = 2x+2
when x = -3/2
y = 2(-3/2) + 2
y = -3+2
y = -1
when x = 4
y = 2(4)+2
y = 8+2
y = 10
Hence the solutions are (-3/2, -1) and (4, 10)

Answer:
0.088.
Step-by-step explanation:
0.22 * 0.4
Now 22 * 4 = 88 and
there are 3 numbers after the decimal points in 0.22 and 0.4 so there has to be 3 numbers after the decimal point in the answer, so it's:
0.088.

Solve the system by substitution y=2x-9, y=-2x+15
Answer:
This system has no solutions
Step-by-step explanation:
y=2x-9,
y=-2x+15
by substitution:
2x - 9 = 2x + 15
2x - 2x = 15 + 9
0 ≠ 24
This system has no solutions

Explain, with details, why |−10|>|3|. Plz help tell why 10 is bigger than three 15 point
Answer:
|-10| is bigger than |3| because when taking the absolute value (the vertical line) of a number, you are counting how far away from 0 it is meaning that both 10 and -10 are 10 spaces away from 0. The negative doesn't matter.

Given the following 30-60-90 triangle , find the value of x and y Round to the nearest tenth x = 5.2 X = 6 Y = 6 Y = 5.2
Step-by-step explanation:
tan30° = Opposite/Adjacent = 3/x.
=> 3/x = √3/3, x = 3√3 = 5.2.
sin30° = Opposite/Hypotenuse = 3/y.
=> 3/y = 1/2, y = 6.
The correct answer is the 1st and 3rd options.
