<h3>How to solve for x?</h3>
The complete question is in the image
The given parameters are:
y = 12 cm
The value of x is calculated using the following sine ratio
This gives
Multiply by 12
Evaluate
x = 8.5
Hence, the value of x is 8.5 cm

You use subtraction in this operation:
70 seashells - 19 seashells = 51 seashells
Thus, Joan is given 51 seashells.
Answer: Choice C
The pink equation is y = 2x-3
The yellow equation is y = -2x+1
Notice how the pink equation crosses the y axis at (0,-3) or at -3 on the y number line. This tells us that the pink equation has a y intercept of -3. So b = -3
This only happens with the equation y = 2x-3. The other equations do not have a y intercept of -3. So this quickly rules out the other choices leaving C as the only answer.
An alternative is to find two points on the pink line, such as (0,-3) and (1,-1). Then find the slope of the line through those points. You should find the slope to be m = 2. So m = 2 and b = -3 leads to y = 2x-3. Follow similar steps for the yellow line as well.
Answer: 192 is the answer
Step-by-step explanation:
|-3 x 64|
3x4 is 12 then you add the one above the 6
next you do 3x60+1 and you get 190 so then you add the 2 that was left over to get 192 as your answer
Answer: 5 5/7
Step-by-step explanation:
Number of pizza bought = 20
Fraction of pizza ate = 2/7
Therefore, the number of pizzas that have been eaten will be:
= Fraction of pizza eaten × Number of pizza bought
= 2/7 × 20
= 40/7
= 5 5/7
Therefore, 5 5/7 pizza have been eaten
