6)
80+160+100+8x+8+5x+10=540
13x + 358 = 540
13x = 540 -358
13x = 182
x = 182/13
x = 14
answer x =14
7)
7x+13=8x-8
8x-7x=13+8
x = 21
answer x = 21
It can't be the first one because if y was 5 and x is 0 that would make both sides equal.
It's not the last one because if y was 1 and x is 7 that would make the right side bigger and that's not correct.
Your answer should be - B. (1, 7)
I hope it helps.
- Triangle Inequality Theorem: States that the sum of any two sides of a triangle is greater than the length of the third side;
So for this, we are applying the triangle inequality theorem. If any of the inequalities are not true, then this cannot be a triangle. (Let A = 7.7, B = 4.0, and C = 1.7)
<u>Since the second inequality is false, these lengths cannot form a triangle.</u>
Answer:
C. 1/10
Step-by-step explanation:
To find the value of a digit in a number, set all the other digits to zero.
The value of the 5 in 634,952 is 000,050 = 50.
The value of the 5 in 43,597 is 00,500 = 500.
We want to find the multiplier k such that ...
50 = k×500 . . . . . . . 50 is "k" times 500
Divide by 500 to see ...
50/500 = k = 1/10
The value of 5 in the first number is 1/10 times the value of 5 in the second number.
