Answer:
37
Step-by-step explanation:
To find the answer to this equation, we need to substitute 5 into where x is in the original equation.
f(x) = 8x-3
f(5) = 8(5)-3
f(5)= 40-3
f(5)= 37
and that's it! no further simplifying.
the answer is 0.56, because there’s 56 shades squares.
Explanation: there’s 100 squares, 56 are shaded 56/100.
Answer:
Each cookbook cost $15.15.
Step-by-step explanation:
Since the statement indicates that four cookbooks and one novel cost $68.75, you can write the following equation:
4x+y=68.75, where:
x is the price of cookbooks
y is the price of novels
Also, given that the novel cost 7 dollars less than a cookbook, you can write the following equation:
x=y+7
Now, you can replace x=y+7 in the first equation:
4(y+7)+y=68.75
4y+28+y=68.75
5y=40.75
y=40.75/5
y=8.15
Now, you can replace the value of y in x=y+7:
x=8.15+7
x=15.15
According to this, the answer is that each cookbook cost $15.15.
The value of x is 21√2/2
The correct option is (A)
<h3>What is Trigonometry?</h3>
Trigonometry is a branch of mathematics that studies relationships between the sides and angles of triangles.
In triangle having angle 60.
sin 60 = P/ 7√3
√3/2= P/7√3
2P= 21
P= 21/2
Now again
cos 45= 21/2/x
1/√2 = 10.5/x
x= 21√2/2

#SPJ1
Answer:
91
Step-by-step explanation:
Let
x = first number
x+1 = second number
x+2 = third number
x+3 = fourth number
Total = 182
x + x + 1 + x + 2 + x + 3 = 182
4x + 6 = 182
Subtract 6 from both sides
4x + 6 - 6 = 182 - 6
4x = 176
Divide both sides by 4
x = 176 / 4
= 44
x = 44
x = 44
x+1 = 44 + 1 = 45
x+2 = 44 + 2 = 46
x+3 = 44 + 3 = 47
Sum of the two middle numbers = 45 + 46
= 91
