4. Consider the expression 9 + 3 x 2 exponent 2 - 1 x 4
(a) What is the value of the expression? Show your work.
(b) How does the value change when grouping symbols are placed around 22 – 1? Show your work.
Answer:
a) 17
b) 45
Step-by-step explanation:
a) [tex]9+3 x 2^{2} - 1 x 4[/tex]
use pemdas first,
[tex]2^{2}\\[/tex] = 4
3x4 = 12
1x4 = 4
now the equation is [tex]9+12 - 4[/tex]
9+12 = 21
that makes the equation 21-4
21-4 = 17
a) 17
now for b
b)
the equation would then be [tex]9+3 x (2^{2} - 1) x 4[/tex]
so youd use pemdas as always
start in the parenthases
[tex]2^{2}[/tex] = 4
4-1 = 3
the equation is now [tex]9+3 x 3 x 4[/tex]
now, multiply 3x3x4
3x3 = 9
9x4 = 36
now the equation is 9+36
9+36 is 45
b) 45
hope this helped!
Answer:
A) 17 B) 45

1. 4(1-3x)+7x=9
2. 9-5x=12-(6x+7)
Answer:
1.) x = -1
2.) x = -4
Step-by-step explanation:
1.) 4(1 - 3x) + 7x = 9
=> Use distributive property:
4 - 12x + 7x = 9
=> Combine like terms:
4 - 5x = 9
=> Isolate 5x:
-5x = 5
=> Isolate x:
x = 5/-5
=> Simplify:
x = -1
2.) 9 - 5x = 12 - (6x + 7)
=> Use distributive property:
9 - 5x = 12 -6x - 7
=> Combine like terms:
9 - 5x = 5 - 6x
=> Isolate x to one side:
9 + x = 5
x = -4
Hope this helps!

2 2/3 divided by 1 3/5?
Answer:
1.67 or 5/3
Hope this helps
Answer:
1 2/3
Step-by-step explanation:
First:
Convert any mixed numbers to fractions.
Then your initial equation becomes:
[tex]\frac{8}{3}[/tex] ÷ [tex]\frac{8}{5}[/tex]
Applying the fractions formula for division,
= [tex]\frac{8}{3} x \frac{5}{8}[/tex]
=[tex]\frac{40}{24}[/tex]
Simplifying 40/24, the answer is
1[tex]\frac{2}{3}[/tex]

Answer:
x = 8
Step-by-step explanation:
The sum of two interior angles in a triangle is equal to the exterior angle that's supplementary to the third interior angle:
7x + 6 + 22 = 9x + 12 add like terms
7x + 28 = 9x + 12 export like terms to the same side of the equation
28 - 12 = 9x - 7x
16 = 2x divide both sides by 2
8 = x

Write the equation of the line that passes through the given points
(0,- 4) and (5,4)
Answer:
y=8/5x-4
Step-by-step explanation:
1:find the slope
[tex]\frac{4+4}{5-0} =\frac{8}{5}[/tex]
slope/m=8/5
2: solve for b using Y=mx+b
plug in the numbers to find b (the x and y get from one set of the points your given and the m is the slope)
Y=mx+b
y=4
m=8/5
x=5
4=8/5(5)+b
4=8+b
-4=b
than to put all the in y=mx+b form just plug in the b and m

Please help haha imm failing math 5(x−2 2/5)=−5.2
Answer:
x= 1.36
Step-by-step explanation:
Answer:
Step-by-step explanation:
5(x−2 2/5) = −5.2
1. We need to use distibutaive property
5×x and 5×-2.4
5x - 12 = -5.2
2. We need to get x alone.
5x - 12 = -5.2
-12 -12
5x = 6.8
3. We need to divide
5x = 6.8
/5 /5
x = 1. 36
check:
5(1.36−2 2/5)=−5.2
6.8 - 12 = 5.2

Name the property used to make the conclusion:
3. If x + 7 = 23, then x = 16.
7. If x - 24 = 25, then x = 49.
a. addition property of equality
b. subtraction property of equality
c. multiplication property of equality
d. division property of equality
e. symmetric property of equality
f. substitution property of equality
Note: They said 3. is NOT A and 7 is NOT B
Answer:
3. B, 7. AStep-by-step explanation:
3. If x + 7 = 23, then x = 16
You need to subtract 7 from both sides.Correct choice is B7. If x - 24 = 25, then x = 49.
You need to add 24 to both sides.Correct choice is AThe population of a town after t years is represented by the function f(t)=7,248(0.983)t. What does the value 0.983 represent in this situation?
