Isolate the a. Note the equal sign. What you do to one side, you do to the other.

Add 5 to both sides

-5 (+5) + 1/5a = 4 (+5)

1/5a = 9

Isolate the a. Multiply 5 to both sides

(5)(1/5)a = 9(5)

a = 9 x 5

a = 45

45 is your answer for a.

hope this helps

176 rounds up to 180
17 rounds up to 20
The fact we're rounding up both times means we'll have an overestimate
estimate = 180*20 = 3600
actual result = 176*17 = 2992

ALGEBRA 2 QUESTION URGENT HELP PLEASE!!

NARA [144]

Answer:

d. the quantity of negative twenty plus sixteen i all over forty one.

Step-by-step explanation:

We want to simplify the complex number:

$\frac{\sqrt{-16} }{(3-3i)+(1-2i)}$

We rewrite to obtain:

$\frac{\sqrt{16}\times \sqrt{-1} }{(3+1)+(-3i-2i)}$

Recall that: $\sqrt{-1}=i$ and $-1=i^2$

We simplify to get:

$\frac{4i}{4-5i}$

We rationalize to get:

$\frac{4i}{4-5i}\times\frac{4+5i}{4+5i}$

$\frac{4i(4+5i)}{(4-5i)(4+5i)}$

$\frac{16i+20i^2}{4^2+5^2}$

$\frac{16i-20}{16+25}$

$\frac{-20+16i}{41}$

The correct answer is D

Mrs. Jones buys 7 t shirts and 6 hats for $86. The price of each t shirt is $3 more than the price of each hat. How much does Mr

Maslowich

The price of 1 hat is $ 5 and price of 1 t-shirt is $ 8

<em><u>Solution:</u></em>

Let "s" be the price of 1 shirt

Let "h" be the price of 1 hat

<em><u>Given that Jones buys 7 t-shirts and 6 hats for $86</u></em>

Therefore, we can frame a equation as:

price of 1 shirt x 7 + price of 1 hat x 6 = 86

$s \times 7 + h \times 6 = 86$

7s + 6h = 86 ------ eqn 1

<em><u>Also given that The price of each t shirt is $3 more than the price of each hat</u></em>

price of 1 shirt = 3 + price of 1 hat

s = 3 + h -------- eqn 2

<em><u>Let us solve eqn 1 and eqn 2</u></em>

Substitute eqn 2 in eqn 1

7( 3 + h ) + 6h = 86

21 + 7h + 6h = 86

21 + 13h = 86

13h = 86 - 21

13h = 65

From eqn 2,

s = 3 + h = 3 + 5 = 8

Thus price of 1 hat is $ 5 and price of 1 t-shirt is $ 8
