Which step in the solution contains the first error?
9514 1404 393
Answer:
Step 4
Step-by-step explanation:
In Step 1, the first equation is correctly multiplied by 2.
In Step 2, the two equations from step 1 are correctly added.
In Step 3, the value of x is correctly determined by dividing by 11.
In Step 4, the value of x is incorrectly substituted for y in the original first equation.
The first error is in Step 4.
The age of the older of two boys is twice that of the younger; 5 years ago it
was three times that of the younger. Find the age of each. pls include steps will mark brainiest
Answer: The older boy is now 20, the younger boy is now 10.
Step-by-step explanation: Explanation:
Let the age of the older boy now be y
let the age of the younger boy now be x
y = 2x
y-5 = 3(x-5)
simplifying
y = 3x - 10
substituting for y in equation 1
2x = 3x-10
simplifying
x = 10
substituting into 1
y = 20
Sue is upholstering a rectangular ottoman that measures 21 centimeters by 18 centimeters by 15 centimeters. What will be the total square centimeters of fabric that Sue must use to cover all faces of the ottoman?
Answer:
1926cm²
Step-by-step explanation:
Given
Dimension = 21cm by 18cn by 15cm
The illustration in this question is to determine the surface area of the fabric and this is calculated using the surface area of a cuboid as follows:
[tex]Surface\ Area =2(LB + LH + BH)[/tex]
Where L, B and H are the dimensions.
So,
[tex]Surface\ Area = 2(21 * 18 + 21 * 15 + 18 * 15)[/tex]
[tex]Surface\ Area = 2(378 + 315 + 270)[/tex]
[tex]Surface\ Area = 2(963)[/tex]
[tex]Surface\ Area = 2 * 963[/tex]
[tex]Surface\ Area = 1926cm\²[/tex]
Hence, 1926 cm² of fabrics are needed to cover all surfaces.

Answer: x = 84°.
Step-by-step explanation: The sum of interior angles of a quadrilateral is equal to 360°. We are given three of the interior angles and asked to find the remaining angle. To do this, we can add the three given angles and subtract the sum from 360°. 53° + 125° + 98° = 276°. 360° - 276° = 84°. Thus, x = 84°.
A busload of campers stopped at a dairy stand for ice cream. They ordered 74 cones, some soft serve at 1.50 each and the rest hard pack at 1.25 each. If the total bill was 100, how many of each type of cone were ordered?
Answer:
40 of the hard pack, 33 of the soft serve
Step-by-step explanation:
x1.25+b1.50=100
100÷2=50
40×1.25=50
33×1.50=49.5
self check
50+49.5=100
(40) 1.25 + (33) 1.50 = 99.5, cant go any higher than that because the price was 100. 50 cents isnt going to buy the 1.25 hard pack or the 1.50 soft shell. so the answer would be 40 of the hard pack and 33 of the soft serve

Find the solution set for 8x^-9x=-1
Answer:
[tex]\mathrm{The\:solutions\:to\:the\:quadratic\:equation\:are:}[/tex]
[tex]x=\frac{1}{8},\:x=1[/tex]
Step-by-step explanation:
Given the equation
[tex]8x^2-9x=-1\:\:[/tex]
Add 1 to both sides
[tex]8x^2-9x+1=-1+1[/tex]
[tex]8x^2-9x+1=0[/tex]
as
[tex]\left(8x-1\right)\left(x-1\right)=8x^2-9x+1[/tex]
so the equation becomes
[tex]\left(8x-1\right)\left(x-1\right)=0[/tex]
Using the zero factor principle:
[tex]\:If}\:ab=0\:\mathrm{then}\:a=0\:\mathrm{or}\:b=0\:\left(\mathrm{or\:both}\:a=0\:\mathrm{and}\:b=0\right)[/tex]
so
[tex]8x-1=0\quad \mathrm{or}\quad \:x-1=0[/tex]
solving
[tex]8x-1=0[/tex]
[tex]8x=1[/tex]
[tex]\frac{8x}{8}=\frac{1}{8}[/tex]
[tex]x=\frac{1}{8}[/tex]
also solving
[tex]x-1=0[/tex]
[tex]x=1[/tex]
[tex]\mathrm{The\:solutions\:to\:the\:quadratic\:equation\:are:}[/tex]
[tex]x=\frac{1}{8},\:x=1[/tex]
