Answer:
Value for x cannot be deduced
Step-by-step explanation:
To solve this question we will have to open the bracket first...we will solve using bodmas rule
1/2(10x+5)-3/2=2x+6+3x
Open the bracket
5x+5/2-3/2=2x+6+3x
Let's collect the like terms
5x-2x-3x=6-5/2+3/2
Lcm for the right side is 2
0=12-5+3/2
0=10/2
0=5
Therefore the value for x cannot be deduced due to the fact that x has been cancelled when solving
Answer:
Step-by-step explanation:
Given the inequality
0.21x + 0.05(17 - x) > 2.55 where x is the amount of 21% lotion needed
Given
0.21x + 0.05(17 - x) > 2.55
Open the parenthesis
0.21x + 0.85-0.05x > 2.55
Collect like terms
0.21x-0.05x+0.85>2.55
0.16x+0.85>2.55
0.16x>2.55-0.85
0.16x > 1.7
x > 1.7/0.16
x > 10.625
Hence she will need 21% lotion approximately greater than 10 ounces
You'll set the two expressions equal to 95.
So 2x+119=95
Then 2x=-24
Finally x=-12
Answer:
cos B
Step-by-step explanation:
Let us take a look at angle B
The side adjacent angle B is 24 while the hypotenuse (the side facing the right angle) is 25
The relationship between the adjacent and the hypotenuse can be mapped our using the cosine
So, the cosine is the ratio between the adjacent and the hypotenuse
Hence, cos B = 24/25
The statement A is true
This is because the coordinate intersection would be, naturally, when x = 2 and y = 4
