Which value of x makes the open sentence true?
xeze [42]

Answer:

x=1/2 or 0.5

B. 0.5

Step-by-step explanation:

Step one: Add x to both sides

you then get the equation 7=4x+5

Step two: subtract 5 from both sides

you then get the equation 2=4x

Divide both sides by 4 to undo the multiplication.

2/4=4x/4x

you get x=2/4 which simplifies to 1/2.

Emelina wrote the equation of a line in point-slope form as shown below. (y+4)=3(x+2) What is Emelina’s equation in slope-interc
Sergeeva-Olga [200]

Answer:

y=3x+2

Step-by-step explanation:

We are given equation as

(y+4)=3(x+2)

Since, we have to write equation in slope-intercept form

so, we can use slope-intercept formula

y=mx+b

where m is a slope

b is y-intercept

so, we can write our equation in this form

(y+4)=3(x+2)

Distribute 3

y+4=3\times x+3\times 2

y+4=3x+6

Subtract both sides by 4

y+4-4=3x+6-4

y+4-4=3x+6-4

y=3x+2

So, slope-intercept form of equation is

y=3x+2

Write a mathematical sentence. t is variable.
Kobotan [32]

Answer:

t + 8 = 82

Step-by-step explanation:

I believe they want the temperature at 11, so we would use the variable t to represent that. Then, we need the sum of that temperature and 8 degrees to break the record of 82 degrees, so we would do t, the temperature, added to 8 degrees, which will break the record of 82 :)

Estimate the answer by rounding each fraction to the nearest whole number and then adding.
Natasha_Volkova [10]

Answer:

24

Step-by-step explanation:

<u>First, we round the fractions. </u>

If a fraction is half or more it rounds up, and if the fraction is less than half it rounds down.

7/10 is greater than half so it rounds up and we add 1 to 13 to get 14.

1/8 is less than half so we round down and remove the fraction so we are left with 10.

<u>Then we add.</u>

14+10=24
