Answer:
The minimum packs of sausages that he needs is 1 and he needs 2 packs of rolls
Step-by-step explanation:
1 pack of sausages contains 5 sausages and 1 pack of rolls contains 4 rolls. Collin needs the same number of sausages and rolls. He needs 2 packs of bread rolls because 4 x 2 is 8 which means there is enough
hope this helps
Answer:
True
Step-by-step explanation:
16x
Both of these expressions are similar expressions, therefore you can simply add the number in front of the 'x'
6 + 10 = 16
Therefore, 6x + 10x = 16x
Answer:
<u>Option B. Side YZ is the same length as side Y'X'.</u>
Step-by-step explanation:
XYZ is reflected across the y-axis and then translated down 6 units to form X'Y'Z'.
So, X' is the image of point X
Y' is the image of point Y
Z' is the image of point Z
And ΔXYZ ≅ ΔX'YΔ'Z'
And the corresponding length are congruent
We will check the options:
A. X has the same measure as X'. ⇒ True
B. Side YZ is the same length as side Y'X'. ⇒ Wrong
Because YZ will be translated to Y'Z'
C. Z has the same measure as Z'. ⇒ True
D. Side XZ is the same length as side X'Z'. ⇒ True
<u>So, The answer is option B. Side YZ is the same length as side Y'X'.</u>
- If the square of a number is added to 8 times the number, the result is 100. Find x.
Let's take the number as 'x'.
- Square of x = x²
- 8 times x = 8x
We are given that, 8x + x² = 100
Now, let's solve for x.

Quadratic equations such as this one can be solved by completing the square. In order to complete the square, the equation must first be in the form x²+bx=c.
Divide 8, the coefficient of the x term, by 2 to get 4. Then add the square of 4 to both sides of the equation. This step makes the left-hand side of the equation a perfect square.
Square 4.
Add 100 to 16.
Factor x²+8x+16. In general, when x²+bx+c is a perfect square, it can always be factored as 
.
Take the square root of both sides of the equation.
Simplify.
Subtract 4 from both sides of the equation.
- x can be either of these values.
