Answer:
(a) x=5
(b) x= -1 1/3
(c) x= 1
Step-by-step explanation:
(a) (b) (c)
2(x-3)=4 −3(2x+1)=5 a(bx+c)=d
x−3=4/2 2x+1= − 5/3 d^1−1
x−3=2 2x= -5/3-3/3 d^0
x=2+3 2x= -5-3/3 x=1
x=5 2x= -8/3*2
x= -8/6
x= -4/3

determine the simple interest when:
principal is $890, interest rate is 4.25% and the time is over 2 years
Answers
Answer:
$75.65
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 4.25%/100 = 0.0425 per year,
then, solving our equation
I = 890 × 0.0425 × 2 = 75.65
I = $ 75.65
The simple interest accumulated
on a principal of $ 890.00
at a rate of 4.25% per year
for 2 years is $ 75.65.
A poll is taken to see which candidate students will elect as class president. 43% of
students say they will vote for Alessandra. The poll has a margin of error of 3%, so the
least and greatest percent she could receive is represented by la – 431 = 3, where a is
the actual percent of students that vote for Alessandra. What is the lowest percentage of
votes she could receive?
Answers
Answer:
The lowest percentage of votes she could receive is 40%
Step-by-step explanation:
43% of students say they will vote for Alessandra, with a margin of error of 3%.
This means that between 43% - 3% = 40% and 43% + 3% = 46% of the students will vote for Alessandra.
This means that the lowest percentage of votes she could receive is 40% and the highest is 46%.
what is the y - intercept of y-8 = 2x *
Answers
Answer:
(0,8)
Step-by-step explanation:
First, we must arrange this equation into slope-intercept form, or y=mx+b form.
Equation: y-8=2x
Add 8 to both sides: y=2x+8
Now that the equation is in slope-intercept form, it is easy to find the y-intercept, as it is just the b-value.
In this case, the b-value is 8, so the y-intercept is (0,8).
Let me know if this helps!
The y-intercept of the equation y - 8 = 2x is 8. This means that the line intersects the y-axis at the point (0, 8), where the y-coordinate is 8.
To find the y-intercept of the equation y - 8 = 2x, we need to set x to zero and solve for y.
Let's substitute x = 0 into the equation:
y - 8 = 2(0)
y - 8 = 0
y = 8
Therefore, the y-intercept of the equation y - 8 = 2x is 8. This means that the line intersects the y-axis at the point (0, 8), where the y-coordinate is 8.

Answer:-43 + 9x = 0
Step-by-step explanation:Simplifying
9x + -43 = 0
Reorder the terms:
-43 + 9x = 0
Solving
-43 + 9x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '43' to each side of the equation.
-43 + 43 + 9x = 0 + 43
Combine like terms: -43 + 43 = 0
0 + 9x = 0 + 43
9x = 0 + 43
Combine like terms: 0 + 43 = 43
9x = 43
Divide each side by '9'.

are 4/5 and 1/2 equivalent explain
Answers
Answer:
They are not equivalent
Step-by-step explanation:
4/5 can equal to .80 to 80%
While 1/2 on the other hand
1/2 can equal to .50 to 50%
4/5≠1/2
Answer:
no they are not equivalent
Step-by-step explanation:
if you look at 1/2 you can already infer that in decimal form it is .50 (so its half of 100, sorry if that doesn't make sense!), and if we look at 4/5 we can tell that in decimal form it is .80 because 100÷5 =80. so therefore, 4/5 and 1/2 are NOT equivalent.

Varsity = at least 90% = 350 times 90% = 315
Anything 315-350
Jr Varsity A = 70-89%
350 times 70% = 245
350 times 89% = 311.5
Jr Varsity b = 50-69%
350 times 50% = 175

the range for a list of numbers is 7. the smallest value is 4. what is the largest value in the list
Answers
Answer:
7
Step-by-step explanation:
The largest value in the list is 11.
What is list?A list is a structure consisting of an ordered set of numbers.
What is the range?"The range is the difference between the smallest and highest numbers in a list."
For given example,
The range for the given list is 7 and the smallest value is 4.
Let R be the range of the list.
⇒ R = 7
Let S be the smallest value in the list.
⇒ S = 4
Let the largest value in the list be L.
⇒ R = L - S
⇒ 7 = L - 4
⇒ L = 7 + 4
⇒ L = 11
Therefore, the largest value in the list is 11.
