What number to be added to each of the number 6,16,36 and 76 to be in proportion?
Answer:
[tex] \pink{ \pmb{SOLUTION:-}}[/tex]
Here,
Let x must be added.[tex]\displaystyle{ \frac{6 + x}{16 + x} = \frac{36 + x}{76 + x} }[/tex]
[tex](6 + x)(76 + x) = (36 + x)(16 + x)[/tex]
[tex]456 + 6x + 76x + {x}^{2} = 576 + 36x + 16x + {x}^{2} [/tex]
[tex]82x + 456 = 576 + 52x[/tex]
[tex]82x - 52x = 576 - 456[/tex]

Answer:
3 30 page printers, 10 70 page printers
Step-by-step explanation:
x + y = 13
40x+70y = 820
Solving for y in first equation gives: y = 13 - x
Plug into second equation: 40x + 70(13 - x) = 820
40x + 910 - 70x = 820
-30 x = -90
x = 3
Plug into original equation: 3 + y = 13
y must = 10.

An architect drew the blueprint for a new office building. He used a scale in which 1 inch represents 7.5 feet. The floor of an office in the building will have actual dimensions of 14 feet by 24 feet. What will the dimensions on the blueprint be?
A.
105 inches by 180 inches
B.
21.5 inches by 31.5 inches
C.
6.5 inches by 16.5 inches
D.
1.87 inches by 3.2 inches
Since we know the scale factor of 1 inch represents 7.5 feet, we can plug in the dimensions for the scale on which the architect drew.
For 14 feet, we can multiply 14 by 1 inch/7.5 feet to get a product of 1.87 inches. Then, we can do the exact same thing with the other width of the floor, which is 24. 24 × 1/7.5 = 3.2
The final dimensions of the blueprint will be D, 1.87 inches by 3.2 inches.

5(3 + 4) − 2 = 7 − 3(−2 + 11)
Answer:
33 = - 20
Step-by-step explanation:
In this equation you have to use BEMA or PEMDAS (however you learned it) ot solve. (Brackets, Exponents, Multiplcation/Divison, Addition/Subtraction) or (Parentheses, Exponents, Multiplication, Division, Addition, SUbtraction)
5(3 +4) - 2 would be simplified down first to
5(7) -2 because parentheses are the first thing you do in any equation like this.
35 -2 because multiplication and divison are next due to the fact there are no exponents
33 because subtraction is last. You then do the same to the other side.
7 -3 (-2 +11)
7 + -3(9) (you can change the minus three to a plus negative three to make the next step more clear)
7 + -27
-20
33 = -20

If a marble is randomly chosen from a bag thay contains exactly 8 red marbles, 6 blue marbles, and 6 white marbles, what is the probability that the marble will not be white?
Answer: 7/10
Step-by-step explanation:
The probability of an event can be calculated as:
[tex]P(E)=\frac{n(F)}{n(T)}[/tex]
Where n(F) is favorable outcomes and n(T) is total possible outcomes.
The total number of marbles can be obtained as,
8 + 6 + 6 = 20
The probability of marble being white can be calculated as,
[tex]P(W)=\underline{\frac{6}{20}}[/tex]
Now, the probability of the marble not being white can be evaluated as,
[tex]\begin{aligned}P^{\prime}(W) &=1-\frac{6}{20} \\&=\frac{20-6}{20} \\&=\frac{14}{20} \\&=\frac{7}{10}\end{aligned}[/tex]
Therefore, the probability of the marble not being white is 7/10
