Step-by-step explanation:
3(-x+2x+1)=x-1
3(x+1)=x-1
3x+3=x-1
3x-x=-1-3
2x=-4
x=-2
I'm sorry but I'm not into square roots yet :(
Answer:
y=1/2x+3/4
Step-by-step explanation:
By seeing the proportion, we get that approximately, 870 g of rice is required and 130 g of meat is required for the recipe.
We are given that a recipe for two people requires 1kg of rice to 150 g of meat.
That is the proportion of rice to meat is:
1 kg : 150 g
1000 g : 150 g
100 : 15
20 : 3
Now, we are also given that 1 kg that is 1000 g of dish is to be prepared.
Let the portion of rice in it be x.
Portion of meat = 1000 - x
ATQ:
20 : 3 :: x : 1000 - x
20 / 3 = x / (1000 - x)
20,000 - 20 x = 3x
23 x = 20,000
x = 20000 / 23 = 870 ( approx.)
1000 - x = 1000 - 870 = 130.
Therefore, by seeing the proportion, we get that approximately, 870 g of rice is required and 130 g of meat is required for the recipe.

Answer:
we know that
Vertical Angles are the angles opposite each other when two lines cross. They are always congruent to one another
in this problem
∠A and ∠B are vertical angles
so
∠A=∠B
we have
∠A=
∠B=
equate angle A and angle B
solve for x
therefore
the answer is
the measure of angle A is
