Answer:

1) The system of equations is $5x+4y=75$ and $x+y=18$

2) The first number is $3$ and the second number is $15$

Step-by-step explanation:

1) Let be "x" the first number and "y" the second number.

Remember that:

a- The word "times" indicates multiplication.

b- A sum is the result of an addition.

c- "Is" indicates this sign: $=$

Then, the sum of 5 times "x" and 4 times "y" is 75, can written as:

$5x+4y=75$

And "The sum of the two numbers is 18" can written as:

$x+y=18$

Therefore, the System of equations is:

$\left \{ {{5x+4y=75} \atop {x+y=18}} \right.$

2) You can use the Elimination Method to solve it:

- Multiply the second equation by -5, add the equations and then solve for "y":

$\left \{ {{5x+4y=75} \atop {-5x-5y=-90}} \right.\\......................\\-y=-15\\\\y=15$

- Substitute the value of "y" into any original equation and solve for "x":

$x+15=18\\\\x=18-15\\\\x=3$

Rewrite 8x - 7 as the product of two factors

kykrilka [37]

Answer:

factors are any group of number or expressions which, when multiplied, produce another number or expression.

Basic example: 4 can be broken into 2 factors---2 and 2. 2 times 2 = 4

Example using an unknown:

2X + 6 = 2 * (X + 3)

In the given problem, there is no whole-number common factor. A normal convention would be to factor based on the unknown term----thus 8X is factored into 8 and X.

So: 8X + 7 = 8 ( X + 7/8 )

The following would also be correct:

8X + 7 = 4 ( 2X + 7/4 )

I need help on this.

liraira [26]

If the triangles are similar, the proportion of the legs on the left to the legs on the right will be equal. This proportion would look like:

$\frac{2x+1}{3x}=\frac{10}{14}$

(You needed to combine the orange segment and the yellow segment to find the total length of the large triangle).

Now, cross multiply and solve for x:

28x+14=30x

<em>*Subtract 28x from both sides to isolate the variable*</em>

14=2x

<em>*Divide both sides by 2*</em>

7=x

Hope this helps!!

State a conclusion that seems reasonable.

Well, if there are 12 eggs grouped together, and 5 of them hatch to be snakes.... More than likely the other 7 will also turn out to be snakes because the eggs are all grouped together.
