Answer:
The numbers are 10 and -2.
Step-by-step explanation:
This question is solved using a system of equations.
I am going to say that:
The first number is x
The second number is y.
A first number plus twice the second number is 8.
This means that:
[tex]x + 2y = 8[/tex], that is, [tex]x = 8 - 2y[/tex]
Twice the first number plus the second totals 19
So
[tex]2x + y = 19[/tex]
Since [tex]x = 8 - 2y[/tex]
[tex]2(8 - 2y) + y = 19[/tex]
[tex]16 - 4y + y = 19[/tex]
[tex]-3y = 3[/tex]
[tex]y = -\frac{3}{3}[/tex]
[tex]y = -1[/tex]
[tex]x = 8 - 2y = 8 - 2(-1) = 8 + 2 = 10[/tex]
The numbers are 10 and -2.

The enrollment at Alpha-Beta School District has been declining 4% each year from 1994 to 2000. If the enrollment in 1994 was 1575, find the 2000 enrollment.
Answer:
the 2000 enrollment is 1,512
Step-by-step explanation:
The computation of the 2000 enrollment is as follows;
Since the enrollment is fall by 4% each year from 1994 to 2000 so the 2000 enrollment would be
= 1994 enrollment × (1 - 0.04)
= 1,575 × 0.96
= 1,512
Hence, the 2000 enrollment is 1,512
triangle KLM ~ triangle KCD are similar. Solve for x.
Answer:
x=14
Step-by-step explanation:
28/16 = 1.75
1.75 is the constant of proportionality
63/1.75 = 36
therefore, 2x+8 should be equal to 36
2x+8 = 36 >> subtract 8 from both sides
2x = 28 >> divide both side by 2 to get x alone
x = 14

Is 1 + 4(3x - 10) - 12x equivalent to -9? EXPLAIN and show your work.
Answer:
Since you have to distribute the 4 to both terms in parentheses, the equation is simplified like this:
1 + 12x - 40 -12x
= 1 - 40
= -39
Step-by-step explanation:
Answer: No
Step-by-step explanation:
1 + 4(3x - 10) - 12x = 9
simplifies to
1+12x - 40 -12x =9
combine like terms to get
-39 = 9
This is not possible so the answer is no.

A 6-meter garden row is divided into 5 equal-sized sections to plant onions
Answer:
1.2 m
Step-by-step explanation:
The question has missing details, however a possible question could be to determine the length of each section.
This is calculated by dividing the rowlength of the garden, by length of each section.
Section Length = Row length ÷ Number of section
Section Length = ,6m ÷ 5
Section Length = 1.2m

How many quarters make a whole?
d) How many fifths make a whole?
e) How many tenths make a whole?
nta Excel in Mathematics - Book 3
108
Answer:
4 quarters
10 tenths
Step-by-step explanation:
Tenths[tex] \frac{1}{10} [/tex]
Quarter[tex] \frac{1}{4} [/tex]
Whole[tex] 1 [/tex]
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
[tex] 1 = \frac{1}{4}+\frac{1}{4}+\frac{1}{4}+\frac{1}{4} [/tex]
∴ There are 4 quarters to make a whole
[tex] 1 = \frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10}+\frac{1}{10} [/tex]
∴ There are 10 tenths to make a whole
