Hey there!☺

$Answer:\boxed{y>x+5}$

$Explanation:$

Solve for y | $-3x+3y>15$

In step 1, we will add 3x to both sides:

$-3x+3y+3x>15+3x\\3y>3x+15$

In our second/last step, we will divide both sides by 3:

$\frac{3y}{3}>\frac{3x+15}{3}\\ y>x+5$

y>x+5 is your answer.

Hope this helps!☺

Hi can someone PLEASE explain this to me i’m STRUGGLING

Answer:

x = 80

Step-by-step explanation:

In a quadrilatoral the interior angle sum always adds up to 360 degrees so to find x you would add all of the interior angle sums and subtract that from 360

115 + 95 + 70 + x = 360 just add the like terms

280 + x = 360 now subtract 280 from both sides so x is alone and you can figure out its value

x= 80

lesya692 [45]

Answer:

162 inches.

Step-by-step explanation:

Please consider the complete question.

Carlos is helping his grandmother make a rug. They have 5 yards of fabric, which is equal to 180 inches. They need an additional of 4 1/2 yards of fabric to finish the trim. How many inches are in $4\frac{1}{2}$ yards?

Let us convert $4\frac{1}{2}$ into improper fraction as:

$4\frac{1}{2}=\frac{4\cdot 2+1}{2}=\frac{8+1}{2}=\frac{9}{2}$

Now, we will use proportions to solve our given problem as:

$\frac{\text{Inches}}{\text{Yard}}=\frac{180}{5}$

$\frac{\text{Inches}}{\text{Yard}}=36$

$1\text{ Yard}=36\text{ Inches}$

To find number of inches in 9/2 yards, we will multiply 9/2 by 36 as:

$\frac{9}{2}\text{ Yards}=\frac{9}{2}\times 36\text{ Inches}$

$\frac{9}{2}\text{ Yards}=9\times 18\text{ Inches}$

$\frac{9}{2}\text{ Yards}=162\text{ Inches}$

Therefore, there are 162 inches in $4\frac{1}{2}$ yards.

Find the base circumference of a cone with height 10 cm and volume 90π cm3 .

Leni [432]

Answer:

Answer is circumference =32.64

Step-by-step explanation:

$given \\ volume \: of \: cone \: = 90\pi \: {cm}^{3} \\ and \: height = 10 \: cm \: \\ to \: find: circumference \\ by \: the \: given \: data \\ volume \: of \: cone = 90\pi \\ \frac{1}{3} \pi {r}^{2} h = 90\pi \\ cancelling \: \pi \: which \: is \: common \: \\ we \: get \\ \frac{1}{3 } {r}^{2} h = 90 \\ we \: know \: that \: h = 10 \\ on \: substituting \: we \: get \\ \frac{1}{3} {r}^{2} \times 10 = 90 \\ dividing \: by \: 10 \: on \: both \: sides \: we \: get \\ \frac{1}{3} {r}^{2} = 9 \\ {r }^{2} = 27 \\ r = 3 \sqrt{3} \\ we \: know \: that \: circumference \: = 2\pi \: r \\ = 2 \times \frac{22}{7} \times 3 \sqrt{3} \\ on \: solving \: the \: above \: mentioned \: we \: get \\ \\ \: = 32.64$

Use the quadratic formula to solve x2 - 5x - 2 = 0.

KIM [24]

Answer:

Step-by-step explanation:

Note: I suppose you typed the question wrong, thus I calculated the question in the picture

$x = \frac{ - b + - \sqrt{{b}^{2} - 4ac} }{2} \\ = \frac{5 + - \sqrt{25 - 4 \times - 2 \times 1} }{2} \\ = \frac{5 + - \sqrt{25 + 8} }{2} \\ = \frac{5 + - \sqrt{33} }{2}$
