Answer:

a = 19

Step-by-step explanation:

a+5/3 (Note: this means a+5 over 3, as in a fraction.)

3 x 8 = a + 5

24 = a + 5

24 + (-5) = (a + 5) + (-5)

19 = (a + 5) - 5

19 = a + 5 - 5

19 = a

a = 19

Hope this helped!

QUESTION :-

Galina-37 [17]

Answer:

92000

Step-by-step explanation:

Given:

I = 5% = 0.05
t = 2 years
Let the sum is x.

Simple interest:

SI = x*2*0.05 = 0.1x

Compound interest:

CI = x*(1 + 0.05)² - x = 1.1025x - x = 0.1025x

The difference is 230:

0.1025x - 0.1x = 230
0.0025x = 230
x = 230/0.0025
x = 92000

Enter an equation in point-slope form for the line. Slope is 9 and (−3, −1) is on the line.

Korolek [52]

Answer:

y+1=9(x+3)

Step-by-step explanation:

Since the equation for point slope form is y-y₁=m(x-x₁)

enter the given points (-3,-1)

y-(-1)=9(x-(-3))

y+1=9(x+3) <-- point slope form

Three lines of crops in a garden form a triangular shape. Strawberries are planted in a 10 ft line and green beans are planted i

Marat540 [252]

Answer:

$p = 19.18$

Step-by-step explanation:

This question is illustrated using the attachment and will be solved using cosine formula

$a^2 = b^2 + c^2 - 2bcCosA$

Let the strawberry side be s, the Green beans be b and the pumpkins be p.

The cosine formula in this case is:

$g^2 = s^2 + p^2 - 2spCosG$

Where

$s = 10$

$g = 18$

The equation becomes

$18^2 = 10^2 + p^2 - 2 * 10 * p * Cos\ 68$

$324 = 100 + p^2 - 20 * p * 0.375$

$324 = 100 + p^2 - 7.5p$

Collect Like Terms

$p^2 - 7.5p + 100 - 324 = 0$

$p^2 - 7.5p - 224 = 0$

Using quadratic formula:

$p = \frac{-b\±\sqrt{b^2-4ac}}{2a}$

Where

$a = 1$

$b = -7.5$

$c = -224$

$p = \frac{-(-7.5)\±\sqrt{(-7.5)^2-4*1*-224}}{2*1}$

$p = \frac{7.5\±\sqrt{56.25+896}}{2}$

$p = \frac{7.5\±\sqrt{952.25}}{2}$

$p = \frac{7.5\± 30.86}{2}$

$p = \frac{7.5 + 30.86}{2}$ or $p = \frac{7.5 - 30.86}{2}$

$p = \frac{38.36}{2}$ or $p = \frac{-23.36}{2}$

$p = 19.18$ or $p = -11.68$

But length can not be negative.

So:

$p = 19.18$

Kiran read for x minutes, and Andre read for 5/8 more than that. Write an equation that relates the number of minutes Kiran read

Liula [17]

Answer: $y = 1.625 x$

Step-by-step explanation:

Here x represents the time taken by Kiran in reading (in minutes) and y represents the time taken by Andrew in reading (in minutes).

According to the question,

Andre read for 5/8 more than kiran.

Thus, The time taken by Andrew(in minutes) = time taken by kiran + 5/8 of time taken by kiran

= $x + \frac{5}{8}\times x$

= $\frac{8}{8} + \frac{5}{8}$

= $\frac{13x}{8}$

= $1.625 x$

Thus, required equation,

$y = 1.625 x$
