Answer:
x= 5
Step-by-step explanation:
We are given;
- Base of the triangle as x
- Length of the leg is 4x-5
- An isosceles triangle has two equal legs and a base.
- The perimeter of the triangle is 35 (spelling mistake in the question)
To get the perimeter of a triangle we add the lengths of all sides of the triangle.
Therefore;
x + 4x-5 + 4x-5 = 35
9x - 10 = 35
9x = 45
x = 5
Thus, the value of x is 5
Answer:
a = 1
b = 3
c = 1
d = 2
e = 6
f = 8
Step-by-step explanation:
Any integer with power as zero = 1
<h3>
For a</h3>
2^x
2^0
= 1
<h3>
For b</h3>
3 * 2^x
3 * 2^0
3 * 1
= 3
<h3>
For c</h3>
2 ^ 3(x)
2 ^ 3(0)
2 ^ 0
= 1
<h3>For d</h3>
2^1
= 2
<h3>
For e</h3>
3 * 2^x
3 * 2^1
3 * 2
= 6
<h3>For f</h3>
2 ^ 3(x)
2 ^ 3(1)
2 ^ 3
2 * 2 * 2
= 8
Only one because there is one variable and the combined coefficients of x are non-zero.
(0.75(x+40)=0.70(x+20), 0.05x=14-30=-16, x=-320)
A ratio of 5:7 means out of 12 books, 5 are in one category and 7 are in another. (The “category” isn’t specified in this problem.)
So here we’re STARTING with 36 books; we want to find a ratio that is equal to 5:7 and adds up to 36. Well 36 = 3(12), and so if we multiply each number in the ratio by 3 as well, we might get what we want. Doing that gives us 15:21, which adds up to 36 and is equal to 5:7. Boom, that’s the answer.
P.S. Here’s a question you can think about: why do ratios stay the same when you multiply each number by the same amount? (For example, why is 3:1 the same as 6:2?)
Answer:
Step-by-step explanation:
1) 792÷ 36=22
2) 1/2 ÷ 3 = 1/6
3) D
4) its 10,00 cause 7.741 x 10 = 77,410
5) the answer in decimal is 60.089
