Answer:

v=1/4

Step-by-step explanation:

simplify both sides

6v+-5/8=7/8

Add 5/8 to both sides

6v+-5/8 +5/8=7/8+5/8

6v=3/2

Divide both sides by 6

6v/6=3/2/6

v=1/4

Answer: v = 2

Step-by-step explanation:

Your equation:

$\frac{6v-5}{8} = \frac{7}{8}$

You can multiply both sides by 8 to eliminate the fraction, which gives you this:

6v - 5 = 7

Then, you can solve for it:

6v = 12

v = 2

In the fallowing diagram, it is shown that mEHG is a right angle, mEHF = x+ 1 and mGHF = 5x+5. Find the value of x, the numerica

GalinKa [24]

Answer:

x = 14

EHF = 15 degree GHF = 75 degree

Step-by-step explanation:

(x+1) + (5x+5) = 90

(x+5x)+ (1+5) = 90

6x + 6 = 90

6x = 90-6

6x = 84

x = 84/6

x = 14

EHF + GHF = 90 degree

EHF = x+1

= 14 + 1 = 15

= 15 degree

GHF = 5x+5

= 14 x 5 (+5) = 70 + 5

= 75 degree

EHF = 15 degree GHF = 75 degree

1- if angle A = 30, then its complementary is -- and its supplementary is

dezoksy [38]

1 - complementary = 90- 30 = 60

suplementary = 180- 30 = 150

2 - area = hb/2 = 360 = hb/2 = h = 72

3 - similar

4- see number 3

5 - asa, ssa, sas

6 - polygon that had all equal angle measures and sides (equiangular and equilateral)

7 - length x width = area so

240 / 24 = 10

8 - line

9 - triangle

10 - 180, as see in question 1

Solve for k <br> 7k+2m = kr + 4m + 3

professor190 [17]

Answer:

$\large\boxed{k=\dfrac{2m+3}{7-r}\ \text{for}\ r\neq7}$

Step-by-step explanation:

$7k+2m=kr+4m+3\qquad\text{subtract}\ 2m\ \text{from both sides}\\\\7k+2m-2m=kr+4m-2m+3\\\\7k=kr+2m+3\qquad\text{subtract}\ kr\ \text{from both sides}\\\\7k-kr=kr-kr+2m+3\\\\7k-kr=2m+3\qquad\text{distribute}\\\\k(7-r)=2m+3\qquad\text{divide both sides by}\ (7-r)\neq0\\\\k=\dfrac{2m+3}{7-r}$

A cell phone plan charges $45.50 a month, plus $0.05 per text message. Write and graph an expression to find how many text messa

scoundrel [369]

Answer:

289 messages

equation: $y=0.05x+45.5$

graph: attached below

Step-by-step explanation:

We can write this in slope-intercept form, or $y=mx+b$ . Since x is defined as the #of text messages, and 0.05 is the cost of a text message, 0.05 will be m. 45.5 is the base price, or the y-intercept, so it will be b.

Plugging in these numbers, we get $y-0.05x+45.5$

now we make y = 60, since that is the total amount they have

$60=0.05x+45.5\\14.5=0.05x\\x=290$

So, they can send 290 messages for 60, but they need the bill under 60, so 1 text message less will be 289, and that's enough.
