1/3z = -5
Step 2: Solve for z
Multiplication Property of Equality [Multiply both sides by 3]: 3 · 1/3z = -5 · 3Simplify [Multiply]: z = -15Step 3: Check
Plug in z into the original equation to verify it's a solution.
Substitute in z: 1/3(-15) = -5Multiply: -5 = -5Here we see that -5 does indeed equal -5.
∴ z = -15 is the solution to the equation.

Plane AXS intersects with which planes? More than 1 answer.
Answer:
Options A and Option B
Step-by-step explanation:
All four sides AX, IX, IS and AS of the base are common in the four side walls of the prism.
In other words, edge AX is common in planes AXU and AXS,
Edge XI is common in planes XIB and AXS,
Edge SI is common in planes EBS and AXS,
Edge AS is common in planes CEA and AXS.
Therefore, plane AXS is intersecting planes AXU and EBS.
Options A and Option B are the correct options.
I have been working all morning on this question and still I don't have the answer to it. What is 2 and 2/4 + 3 and 2/4?
Answer: 2 and 2/4 + 3 and 2/4 = 1.
Step-by-step explanation:
in these type of problems you need to add separately the whole and rational parts:
(2 and 2/4) + (3 and 2/4) = (2 + 3) and (2/4 + 2/4)
= 5 and 4/4
but 4/4 = 1
And also remember that the "and" is equivalent to a "+" sign, then:
5 and 4/4 = 5 + 1 = 6
Then:
2 and 2/4 + 3 and 2/4 = 1.

if 1/2x^2 - 1/4 x + 3 what is the value of x = 8 ?
Answer:
If x=8 then the equation is equal to 33
If 1/2(x)^2-1/4x=3=8 then x=-2.98 and x=3.35
Step-by-step explanation:
Given:
1/2x^2-1/4x+3
Two solutions possible:
If x=8 then 1/2(8)^2-1/4(8)+3=32-2=3=33
If 1/2(x)^2-1/4x+3=8 then .5x^2-.25x-5=0
factoring:
(.707x+2.11)(.707x-2.37)=0
.707x=-2.11 and .707x=2.37
x=-2.98 and x=3.35 rounded to 2 places

Dominic is asking his relatives and friends to contribute $2 each to the school library fund. So far he has collected donations from 23 of his relatives. The expression 2(f+23) represents the total amount of money Dominic expects to receive. What part of the expression represents the total number of people that Dominic expects to contribute $2 to his project?
A
f
B
23
C
f+23
D
2f+23
Answer:
Option C : f+23 is the correct answer.
Step-by-step explanation:
Given that:
Amount Dominic wants everyone to contribute = $2
Number of relatives who have contributed = 23
The expression is;
2(f+23)
As we know that 2 represents the amount and 23 represents the number of relatives who have donated, therefore,
f represents the number of people who would donate to the library fund, and
f+23 represents the total number of people who contributes to the fund.
Hence,
Option C : f+23 is the correct answer.

Mary drew a box and whisker plot for the following data: 23, 10, 12, 30, 26, 8, 25, 18.Find the following: First Quartile: Median: Third Quartile: Range:
Answer:
1st Qtrl: 11
Median: 20.5
3rd Qtrl: 25.5
Range: 22
Step-by-step explanation:
Median = average of 2 middle values (18 + 23) / 2
1st Qtrl = average of 10 and 12 (the lower half of data)
3rd Qtrl = average of 25 and 26 (the upper half of data)
Range = largest value - smallest value; 30 - 8 = 22

Karrem says that the ratio 4:1 is eqivilent to the ratio of 12:9 because 4+8=12 and 1+8 =9 is karreem correct
Answer:
No, Kareem is incorrect.
Step-by-step explanation:
Kareem says that the ratio of [tex]\frac{4}{1}=\frac{12}{9}[/tex] because 4 + 8 = 12 and 1 + 8 = 9
But the correct way to rewrite the ratio 4 : 1 is,
[tex]\frac{4}{1}=\frac{4\times 3}{1\times 3}[/tex]
Which becomes as,
[tex]\frac{4}{1}=\frac{12}{3}[/tex]
Therefore, Kareem is not correct.
Correct ratio equivalent to 4 : 1 is 12 : 3.
