AleksAgata [21]3 years ago

Answer:

<em><u>please mark me a brainliest</u></em>

\frac{2.5 + 1.3 + 2.2 + x}{4}  = 1.8

\frac{6 + x}{4}  = 1.8

6 + X = 1.8 * 4

6 + X = 7.2

X = 7.2 - 6

X = 1.2

So therefore the value of X is 1.2

If x is an integer, what is the least possible value of x for a rectangular lot
AlexFokin [52]

Answer:

k = 13The smallest zero or root is x = -10

===============================

note: you can write "x^2" to mean "x squared"

f(x) = x^2+3x-10

f(x+5) = (x+5)^2+3(x+5)-10 ... replace every x with x+5

f(x+5) = (x^2+10x+25)+3(x+5)-10

f(x+5) = x^2+10x+25+3x+15-10

f(x+5) = x^2+13x+30

Compare this with x^2+kx+30 and we see that k = 13

x^2+13x+30 = 0

(x+10)(x+3) = 0

x+10 = 0 or x+3 = 0

x = -10 or x = -3

The smallest zero is x = -10 as its the left-most value on a number line.

Step-by-step explanation: Hope this helps kind of.

The equation is. -0.5p-2=p how do I solve this??<br> And show my work
ASHA 777 [7]
-0.5p-2=p

Add 0.5 to both sides which would equal
-2=1.5p

Then divide -2 by 1.5p
P=-1.33333333

Help #4-8 please thank you
Olin [163]

Answer:

#4: 130/60, simplified is 13/6 (divide numerator and denominator by 10)

#5: 110/130, simplified is 11/13 (divide numerator and denominator by 10)

#6: 5/12

#7: 4/12, simplified is 1/3 (divide numerator and denominator by 4)

#8: 12/4, simplified is 3, or 3/1 (divide numerator and denominator by 4)

Step-by-step explanation:

#4: Part 1 is 60 miles, and the whole trip is 60 + 20 + 50 = 130 miles

So while #1 was 60 over 130 for "60 to 130", now we'll put the 130 on top of the 60 for "130 to 60" as a spoken ratio

#5: I think they mean add part 1 to part 3, then compare to the whole.

so 60 + 50 = 110, and your answer is 110/130

-------------------------------------

Punch: 3 pints Hawaiian punch, 4 pints of orange juice, 5 pints of ginger ale is the recipe. When you pour that all together, you have 3 + 4 + 5 pints of mixed punch as a total, or 12 pints.

#6: 5 pints of ginger ale to 12 pints of punch: 5/12

#7: 4 pints of orange juice to 12 pints of punch: 4/12

#8 12 pints of the whole drink to 4 pints of orange juice: 12/4
