Answer:

x+x=8

that's mean: 2.x/4 + 4.x/1 = 18/1

we find at least a common multiple of 4 and multiply the units by 4

2x + 16x = 72

18x = 72/:18

x = 4

Answer: 7

suppose: the smaller number is a

the larger number is b

because The sum of two numbers is 8 => a + b = 8 (1)

four times the smaller number is added to two times the larger number, the result is 18 => 4a + 2b = 18 (2)

(1)(2) => a + b = 8

4a + 2b = 18

<=> a = 1

b = 7

=> the larger number is 7

Answer:

$t+0.07t=t(1+0.07)=t(1.07)=1.07t$

Step-by-step explanation:

There are a couple of equivalent expressions to the function $t+0.07t$ . For example:

$t+0.07t$

Factor:

$t+0.07t=t(1+0.07)$

If you add the terms inside the parentheses:

$t(1+0.07)=t(1.07)$

Basically you can add the like terms from the start and get the same result.

$t+0.07t=1.07t$

Therefore:

$t+0.07t=t(1+0.07)=t(1.07)=1.07t$

What is the volume of the right rectangular prism? Enter your answer in the box.

Nutka1998 [239]

Answer:

1000 cm²

Step-by-step explanation:

Given:

Length = 10 cm
Width = 12.5 cm
Height = 8 cm

<u>Formula:</u>

$\text{Volume = Length} \times \text{Width} \times \text{Height}$

Substitute the length, width, and the height of the prism to determine the volume of the prism.

$\implies \text{Volume = 10} \times 12.5 \times 8$

Simplify the right hand side of the equation, as needed;

$\implies \text{Volume = 10} \times 12.5 \times 8$

$\implies \text{Volume =}\ 125 \times 8$

$\implies \boxed{\text{Volume =}\ 1000 \ \text{cm}^{2} }$

Therefore, the volume of the prism is 1000 cm².

Use the diagram to answer the questions

IRISSAK [1]

Answer:

1. B. BD

2. C. 15

3. A. 2

Step-by-step explanation:

1. From the figure,

∠DAB = ∠DAC

Therefore, BD is the bisector of ∠ABC.

2. From the figure, IG = GH

3x = 5x - 10

10 = 5x - 3x

2x = 10

x = 5

So, GH = 5x - 10

= 5(5) - 10

= 25 - 10

= 15

Therefore, GH = 15.

3. From the figure,

∠DAB = ∠DAC

10y = 8y + 4

10y - 8y = 4

2y = 4

y = 2
