SHOW WORK STEP BY STEP
Answer:
500
Step-by-step explanation:
Answer:
500
put the 8,000 into the 40,000 mark. you will get a five and if you tried to put it in the last two, you would get 0. 8000*5=40000 so subtract 40,000 and you should get a 0 there. keep putting the zeroes until you get to the end.

Carlos says that the XYZ is not congruent to PQR because there is no SSA theorem or postulate.
In two or more complete sentences, explain why or why not Carlos is correct. Justify your answer using triangle congruency postulates, theorems, and definitions.
Carlos is correct
Since we don't know the length of sides PR and XZ, the triangles can't be congruent by the SSS theorem or the SAS theorem, and since we don't know the measure of angles Y and Q, the triangles can't be congruent by the ASA theorem, the SAS theorem or the AAS theorem. Therefore, Carlos is correct.
Carlos is correct. Since the angles P and X are not included between PQ and RQ and XY and YZ, the SAS postulate cannot be used, since it states that the angle must be included between the sides. Unlike with ASA, where there is the AAS theorem for non-included sides, there is not SSA theorem for non-included angles, so the triangles cannot be proven to be congruent.
Robert and his younger sister are selling gift wrap to raise funds for the middle school band. Robert's sales are 2.5 times his sister's sales. Their total sales together can be represented by the equation x+2.5x=63 . Which of these statements are true? Choose ALL that are correct. A Robert's sales are represented by x when solving 3.5x=63 . B Robert's sister's sales total $18.00. C Robert's sales are represented by x when solving 2.6x=63 . D Robert's sales total $25.20. E Robert's sister's sales are represented by x when solving 3.5x=63 .
Answer:
B. Robert's sister's sales total $18.00.
E. Robert's sister's sales are represented by x when solving 3.5x = 63 .
Step-by-step explanation:
Let
Robert sister's sales = x
Robert sales = 2.5 * x
= 2.5x
Total sales = Robert sister's sales + Robert sales
63 = x + 2.5x
63 = 3.5x
Divide both sides by 3.5
x = 63 ÷ 3.5
= 18
x = $18.00
Robert sales = 2.5x
= 2.5(18)
= $45.00
A. Robert's sales are represented by x when solving 3.5x=63 .
No
B. Robert's sister's sales total $18.00.
Yes
C. Robert's sales are represented by x when solving 2.6x=63 .
No
D. Robert's sales total $25.20.
No
E. Robert's sister's sales are represented by x when solving 3.5x = 63 .

Step-by-step explanation:
Combine terms: 12a + 26b -4b – 16a.
(a) 4a + 22b,
(b) -28a + 30b,
(c) -4a + 22b,
(d) 28a + 30b
Answer:
(c) -4a + 22b
Explanation:
12a + 26b - 4b - 16a
= (12a - 16a) + (26b - 4b)
= -4a + 22b
Answer:
c, minus 44 a plus 22 B
Step-by-step explanation:
12a + 26b -4b – 16a
=12 a - 16 a + 26b - 4b ( like terms )
= -4a+22b

➤ How to solve ?
⠀⠀⠀⠀
That's quite easy but you need to recall the BODMAS rule .
⠀⠀⠀⠀
BODMAS rule states the correct sequence to solve an equation . First we need to solve the bracket part then solve if any of is present moving further to division then multiplication carrying with addition atlast subtraction
⠀⠀⠀⠀
In this equation we will solve the bracket then we will apply further BODMAS rule
⠀⠀⠀⠀
━━━━━━━━━━━━━━━━━
SolutiOn :
➠ 7x + 31 = 8x - 1 ( 27x + 3 ) -3
➠ 7x + 31 = 8x - 27x - 3 - 3
Now, we will bring the variable on left hand side and constants on right hand side
➠ 7x - 8x + 27x = - 31 - 3 - 3
➠ 26x = -37
➠ x = -37/ 26
➠ x = - 1.42
∴ The value of x is -1.42 .

Answer:
2x + 3y = 10
Step-by-step explanation:
What we know:
Triangle ABC has Segment AB included in the equation 2x + 3y = 5.
Saying that this is scaled up, Segment A'B' has be included in an addition equation. As a result, Choices 1 and 4 are out. Second, the two terms on the left side have to be the same, so Choice 3 is also out.
This leaves Choice 2, which is 2x + 3y = 10
In case you're confused with the pic below:
eq1's line is 2x + 3y = 5
eq2's line is 2x + 3y = 10
poly1 is the triangle formed on eq1's line
poly2 is the triangle formed on eq2's line

Give the slope of any line that is perpendicular to the line y = -1/8 x + 5
Answer:
8
Step-by-step explanation:
To find a slope for a line that is perpendicular to another line, you simply need to take the negative reciprocal of the the original line's slope. In this case we are already given the slope as the coefficient to x: -1/8. The negative reciprocal of that is 8/1, or just 8.

Solve for z: 4 (z+6) -11 = 25
I need to show my work
Answer:
z=3
Step-by-step explanation:
4(z+6)-11=25
add 11 to both sides
4(z+6)-11+11=25+11
simplify
4(z+6)=36
divide each side by 4
(4(z+6))/4=36/4
Simplify
z+6=9
subtract 6 from each side
z+6-6=9-6
simplify
z=3
Answer:
z=3; plug the equation into a calculator

ignore the graph above the one with the dots lol
Answer:
No.
Step-by-step explanation:
Use a vertical line test.
Vertical line test: If you can draw a vertical line and it does not cross two points in the line, then it is a function.
So, we draw a line.
Draw it through 9,0
It intercepts two points so No. This is not a function.
Hope this helps plz hit the crown :D

Equation is in a picture this is for middle school 8th grade
Answer:
the first equation, y = 9/4 x
Step-by-step explanation:
according to the equation for slope-intercept form y=mx+b, the m represents the slope indicating that the 9/4 would be placed there with the exponent of x attached to it. And the y-intercept is represented by the b in the equation, and since it is 0 in this case you will not need to add it in the equation. so your final answer would be y=9/4x
