Answer: the answer is d, she selected a multiple that is not a least common multiple. The least common multiple is the number both sets of numbers share, which  would be 30.

Answer:

Options A and D are correct

Step-by-step explanation:

Here, we want to find the square root of the negative number;

x^2 = -64

x^2 = 64 * -1

x= √64 * √-1

Mathematically we can write the √-1 as i

X = √64 * i

Square root of 64 is plus or minus 8

so x = -8i or 8i

The solutions of an equation are the true values of the equation.

The expression that represents the solution(s) of [tex]\mathbf{8i}[/tex] is [tex]\mathbf{-8i}[/tex]

The equation is given as:

[tex]\mathbf{x^2 = -64}[/tex]

Take square roots of both sides

[tex]\mathbf{x = \pm\sqrt{-64}}[/tex]

Expand

[tex]\mathbf{x = \pm(\sqrt{64} \times \sqrt{-1})}[/tex]

[tex]\mathbf{x = \pm(8 \times \sqrt{-1})}[/tex]

In complex numbers,

[tex]\mathbf{ \sqrt{-1} = i}[/tex]

So, we have:

[tex]\mathbf{x = \pm(8 \times i)}[/tex]

[tex]\mathbf{x = \pm8i}[/tex]

Split

[tex]\mathbf{x = 8i\ or -8i}[/tex]

So, the expression that represents the solution(s) of [tex]\mathbf{8i}[/tex] is [tex]\mathbf{-8i}[/tex]

Answer:

Step-by-step explanation:

An army base had provisions for 300 soldiers for  90 days. After 20 days, there should be provisions enough for 300 soldiers for another 70 days

= 21000 soldier-day

50 soldiers left so there are 300-50 = 250 soldiers left

if they consume food at the same rate, the remaining provisions will last

= 21000/250

= 84 days

Answer:

30.58

Step-by-step explanation:

If you turn the 20% into a decimal you get .25 and do the equation .25x 139. This gives you 30.58

If the seventh-grade class has 139 students then 31 students have 31 students.

percentage, a relative value indicating hundredth parts of any quantity.

Given that Twenty-two percent of the seventh-grade class at Santa Ana Middle School has blue eyes

The number of students in  seventh-grade class are 139.

We have to find the number of students who has blue eyes in Santa Ana Middle School.

Convert 22% to decimal value.

22/100=0.22

Now multiply 0.22 with 139

0.22×139

30.58=31 students

Hence,  If the seventh-grade class has 139 students then 31 students have 31 students.

Step-by-step explanation:

you turn your fraction into a decimal and to find the decimal you take the number and put it out of 100 such as 1/2 is 50/100 therefore meaning you get .50

67 1/2 in fraction form is 135/2 .

Given,

67 1/2 in mixed fraction .

Now to convert mixed fraction to simple fraction follow the following steps,

Multiply the whole number and denominator of the fraction . After that add numerator part to the result of multiplication . Fraction will be formed by keeping the denominator same,

Thus the resultant will be,

67*2 = 134

134 + 1 = 135

Answer: -3

Step-by-step explanation: When you graph this that’s what you get

Answer:

-3

Step-by-step explanation:

the y intercept is when x is 0 on the graph. Since you know x has to be zero, you can substitute x for 0 in the equation:

y = -0.5x0 -3

Now you can ignore that first part of the equation because it equates to 0, and so you get:

y= 0 - 3

which equals:

y=-3

Answer:

X=-4 y=-3

Step-by-step explanation:

Solve by substitution:

Step: Substitute

2x+5 for y in y = −3x−15 :

2x+5+3x=-3x-15+3x ( add 3x to both side)

5x+5=-15

5x+5+-5=-15+-5(add -5 to both sides)

5x=-20

5x/5=-20/5(divide both sides by 5)

X=-4

Step: substitute -4 for x in y=2x+5

Y=2x+5

Y=(2)(-4)+5

y=-3 (simplify both sides of the equation)
