Answer:
1233.68 g
Step-by-step explanation:
Given:
The weights are
1.21 kg
546 mg
23.14 g
Here,
the units of all the weights given are not uniform, also the options are provided in grams
Therefore, we will first convert all the weights in the uniform unit i.e in grams
thus,
we have
1.21 kg = 1210 g
546 mg = 0.546 g
23.14 g
hence,
the total mass = 1210 g + 0.546 g + 23.14 g = 1233.686 ≈ 1233.68 g
Hence, the correct answer is option 4. 1233.68 g
Answer:
$1.25
Step-by-step explanation:
Set up a proportion, use inverse operations, and solve;
cups : price
4 : 5
/4 /4
1 : 5/4
1 : 1.25
1 cup to $1.25
Answer:
x=3,y=7
Step-by-step explanation:
8x+3y=45
2x+3y=27
8x-2x=6x
45-27=18
<u>6</u><u>x</u><u>=</u><u>1</u><u>8</u>
6. 6
x=3
2x+3y=27
2(3)+3y=27
6+3y=27
3y=27-6
<u>3</u><u>y</u> = <u>2</u><u>1</u>
3. 3
y=7
Answer:
y = 
x
Step-by-step explanation:
slope-intercept form: y = mx + b
Given: slope(m) = , point (4, -3)
We already have the value of m, but we need to find the value of b. To do this, input the given values of the slope and the point into the equation:
-3 = (4) + b
Solve for b:
-3 = (4) + b
-3 = -3 + b
0 = b
The value of b is zero. We can now write the equation:
y = x + 0
y = x
The equation written in slope-intercept form is: y = x
