Answer:
84°
Step-by-step explanation:
Let the measures of the triangle be 5x, 7x, 3x.
By interior angle sum postulate of a triangle.
5x + 7x + 3x = 180°
15x = 180°
x = 180°/15
x = 12°
7x = 7*12°= 84°
Measure of the largest angle = 84°
Answer:
I am gonna take a guest and say <em>178</em> for number 3. And for number 4, the answer is <em>44.</em>
Step-by-step explanation:
For number 3, I added 76 and 102 which equals 178. For number 4, I put n+6+3n-10=180 because its a triangle. Do the math and you get n=44. Correct me if I am wrong; I tried my best.
Answer:
B is correct. Your starting amount is 210$ And you're taking away 15$ each time she uses the club,x.
Step-by-step explanation:
Answer:
The linear function model the situation is b = 210 - 15x .
Option (B) is correct .
Step-by-step explanation:
Let us assume that the number of times giselle uses the club be x .
As given
giselle pays $210 in advance on her account at the athletic club.
Each time she uses the club,$15 is deducted from the account.
Let suppose that the money left after giselle uses the club x times is b .
Than the equation becomes
Money left = Amount pay in advance - Deducted amount × Number of times giselle uses the club .
Put all the values in the above
b = 210 - 15 × x
b = 210 - 15x
Therefore the linear function model the situation is b = 210 - 15x .
Option (B) is correct .
Answer:
a = -1/2
Step-by-step explanation:
- 1/4a - 4 = 7/4a - 3
- 1/4a - 7/4a = - 3 + 4
- 8/4a = 1
- a = 1 / 8/4
- a = 1 * 4/8
- a = 4/8
- a = 1/2
a = - 1/2
